the errors be represented by the scatter between PSF fitting results

of minimium mass M sin i = 1.96 Mjup. Sahlmann et al. (2011) derive a
combined astrometric/spectroscopic orbit, using values of P,e,T, and
omega from the spectroscopic orbit of Santos et al. (2010 A&A 512,
A47). They determine the orbit is nearly face-on, yielding an
estimated mass for the companion of 69 +/- 20 Mjup. Thus it can no

01135-3821 BRG 4 The primary star in the system is a known eclipsing binary with a
period of 0.4455 days (Parihar et al. 2009 MNRAS 395, 593). Since the
angular separation is inside of our inner cut-off, we count the system
as a binary here for the purpose of multiplicity statistics, although
it is really a triple system. To estimate the mass of the primary for
the purpose of deriving the mass ratio to the tertiary component
detected in our images, we use the sum of the masses corresponding to
individual spectral types M1 and M3 derived for the eclipsing binary. Jnn2012

01379-8259 TOK 426 HIP 7601 is a nearby (27pc) dwarf also known as GJ 67.1 or HR 512.
According to Wichman et al. (2003 A&A, 400, 293), it is a young
spectroscopic triple detected in X-rays (1RXS J013755.4-825838). GCS
also recognized the star as SB2. Spectroscopic monitoring (Tokovinin,
in preparation) shows that all three components are similar stars of
approximately one solar mass. Here we resolved the outer subsystem AB
and observed its fast motion. In fact it was already resolved at SOAR
on 2011.036 at 221.0deg and 0".044, but this low-quality observation
has not been published. The available data indicate that the period
of AB is 1.35years; the pair completed nearly two revolutions since
its first resolution in 2011. Tok2015c

Chemically peculiar late-B star, initially thought to be a triple,
with spectroscopic period 41.4d and astrometric period 878d. Using
Coralie spectra from 2000-2010, Korhonen et al. (2013 A&A 553, A27)
find a spectroscopic period of 1126d. Spectroscopic data by Pourbaix
et al. (2013) exclude the 40d period, but are insufficient to refine
the Korhonen solution. Their spectroscopic elements are combined
with the Hipparcos astrometry to refine the initial astrometic orbit. Pbx2013

EGG 2 Aa,Ab: This system has spectral type F2 from SIMBAD and parallax of
10.26 +/- 2.92 mas from van Leeuwen (2007). A previous orbit was VlF2007
calculated by Cvetkovic (2008) with period of 109 years and semimajor Cve2008c
axis of 0.344 arcsec. However, our new observation shows that the
system has a much shorter period and smaller semimajor axis. However,
our orbit yields roughly the same total mass, with large uncertainty.
The system appears to have executed nearly a full orbit since the
first speckle observations taken of it in 1985 by McAlister et al.
(1987). More data will be needed to confirm this orbital trajectory,
but if correct, the smaller period makes the system much more
attractive for future study. Hor2015b

02490-1029 BRG 16 The system is precisely at the 3 sigma threshold for statistically
significant exclusion of the background star hypothesis. By chance,
the AB astrometry is just below the criterion (2.7 sigma) and BC is
just above (3.1 sigma), so in principle the BC pair is inconsistent
with chance alignment, if the pair does share a common proper motion
with A. However, the proper motion of the system has of course been
determined based on A, so until the AB physical connection has been
demonstrated to the required accuracy, the 3.1 sigma confidence of the
BC pair is irrelevant. Hence, we label the entire system as
undetermined for now, although it is obviously very likely that the
whole system is indeed bound. Jnn2012

According to Scardia et al. (2001), this orbit is now well defined and Sca2001d
will certainly change little in the future; only the period is still
slightly uncertain. The Hipparcos parallax is 0".02012 +/- 0.00150.
This gives a mass sum of 2.1 Msun +/- 29%, agreeing very well with
expected values for a system of type G0. Compared to the orbit
calculated by Scardia in 1980, the total mass of the system, whose Sca1980e
uncertainty was then 55%, is now much better defined. The dynamical
parallax is 0".0193, well in agreement with the measured parallax.

03052-3725 BRG 18 This target, like BRG 23, gives conflicting information about whether
the AB pair is physically bound. The brightness and color are fully
consistent with B being an M3.5 companion to the M2.0 primary.
Furthermore, the separation is only 0.2", and the whole field is
otherwise empty. This indicates physical companionship. However, the
deviation from the expectation of a background source is only 1.1
sigma, and the companion has moved 3.6 times closer to the background
expectation than its original position where the motion has a 14 sigma
confidence. This, by contrast, suggests a chance alignment. Since the
magnitude of motion is not inconsistent with what could be expected
for orbital motion of a real physical pair, we keep it as binary in
our analysis, but we note that further observations will be necessary
in order to resolve this issue satisfactorily. Jnn2012

The eclipse phenomena, known since historical times (although the time
of minimum brightness was first measured by Montanari on 8 Nov 1670)
was first explained as an eclipsing binary by Goodericke as early as
1782. According to R.G. Aitken, this was verified when it was noted as A__1935f
the second spectroscopic binary based on photographic spectra
obtained by Prof. H.C. Vogel at Potsdam in November, 1889. Belopolsky
discovered a variation in the radial velocity with a period of order
1.8 years, later resolved by Labeyrie and his speckle camera in 1973; Lab1974
the magnitude difference is about 2.5.
The binary, a radio and X-ray source, is triple (and possibly
quadruple, but the variation with the 32 yr period is more probably an
apsidal rotation of the eclipsing pair).
The spectroscopic data were discussed by Hill et al. (1970, 1971). HlG1970

Peterson et al. (2011) orbits of both the outer (CHR 9Aa,Ab) and Ptn2011
inner (CIA 10Aa1,Aa2) are based on VLBI measures combined with
speckle and radial velocity data. Assuming masses of the primary and
secondary of 1.10 and 0.95 Msun, respectively, they derive a mass for
the tertiary of 0.75 +/- 0.01 Msun.

error in T0 (2456238.134d changed to 2456237.634d). Also, they were
unaware of the wide CPM companion, so erroneously refer to the close
pair as Aa,Ab and the CHR pair as AB.

The B component was resolved at Palomar (0.580"). Genet et al. (2013)

AB: known binary, which shows apparently a non-Keplerian motion. Rica
Romero & Zirm (2014) proposed that the motion was caused by an unseen FMR2014c
companion and calculated an astrometric orbit for it with P = 107 yr,
eccentricity 0.61, and photocenter semimajor axis 0".179. Our
observations were able to resolve the predicted subsystem Aa,Ab. For
the time of our observations the orbit predicts a companion position
angle of 43.3 deg, in excellent agreement with the position angle of
44 +/- 1.3 deg measured here. The ratio of the predicted displacement
to the measured separation of 0".50 is r = 0.32 = q/(1+q). Hence, the
mass ratio q = 0.47 (the contribution of the light from Ab to the
photo-center is neglected). The mass of Aa is estimated at 1.16 Msun
from its absolute magnitude, leading to 0.54 Msun for Ab. The absolute
magnitude of Ab corresponds to a smaller mass of 0.33 Msun. This
discrepancy, if confirmed, can be explained by Ab being a close pair
of M-dwarfs, as happens in other known multiple systems, e.g., in kap Tok2013a

respectively) in Riaz et al. (2006), hence it is likely that they form Ria2006
a physical pair. 2MASS J03415581-5542287 is a close (~0.61") binary in

03425+1216 JNN 26 Since the two epochs of observation were acquired over a baseline of
only a few months, there is not yet sufficient motion to confirm
common proper motion of the companion that was detected with AstraLux.
However, the separation between components is rather small (~0.86"),
and the fact that the companion is clearly detected in z' but too
faint in i' implies that it must be very red, as expected for a real
companion. Hence, we count it as a binary system for statistical
purposes. Jnn2012

STF 485 The classification is from Chocol (1980 Bull. Astron. Inst. Czech. 31,
CHR 209 321). The discovery of speckle companion CHR 209 Ea,Eb with a period
WSI 20 of some 60 y confirms the third body model advocated by Mayer et al.
HZG 2 (1994 A&A 288, L13) based on the appearance of the spectrum and
HLM 3 variations in the time of light curve minimum (they suggest a third
body period of 50.7 y). Another light curve solution is given by
Harries et al. (1998 MNRAS 295, 386). The B component was also
observed and appeared to be single. Classification of the B component
is from the WDS. Msn1998a
This complex multiple system has had numerous identification errors
due to various difficulties. The diagram of Lewis in his catalog of L__1906b
the Struve pairs, which seemed a good first step, was hampered by the
quadrant error of the pair he designated Ca. This quadrant error was
repeated in the ADS, IDS, and in earlier editions of the WDS. In the
ADS (where this pair is listed as #2984, but note that #2989 is part
of this system, too) the errors multiplied. The pair Holmes AF (WDS
designation HLM 3AF) is apparently the same as STF 485Ac. Inspection
of scanned images of this region of the sky have allowed the
Hertzsprung pairs (HZG 2) whose components are given within
quotation marks in the ADS to be identified. Of the HZG pairs, the
"CD" pairing is the same as STF 484AC and the "CE" pairing is the
same as STF 484AB. The ADS note to the "AJ" pairing of HZG 2 is a
typographical error. The correct position angle is 77 degrees, which
corresponds to the AD (now AO) pair. Below outlines the changes from
the WDS 2001.0 to the current version.

CHR 209 Ea,Eb: The primary of this pair is the Beta Lyrae-type O9/B0 eclipsing
system SZ Cam, with a period of 2.698d. The Gorda et al. (2007) orbit Grd2007a
is based on changes in the period of SZ Cam to determine P, omega, e, Grd2007b
and T, and speckle measures to derive i, Omega, and a. They derive a
distance of 1125 +/- 135 pc, which exceeds by 30% the 800pc distance
to the open cluster NGC 1502; they conclude that SZ Cam is not a
member of the cluster. The mass of the eclipsing pair (Ea) is 28.5
+/- 0.5 Msun, that of the third body (Eb) 23.4 +/- 2.4 Msun.
Eb is also a close binary.

The secondary is SB2 (F8+G6), with period 17.6 days for Ba,Bb; RV
residuals indicate the presence of a more distant Bc companion. Based
on spectroscopic observations obtained at CfA 1988-2004, Torres (2006)
derived an orbit for Bab,Bc with period 9.447 +/- 0.017 yr. Mass for
the A component is determined to be 2.60 +/- 0.5 Msun. Inclination
angle for the Ba,Bb orbit is 53.5 +/- 0.5deg, yielding masses 1.19 and
1.02 Msun for Ba and Bb. Bc appears to be over-massive; based on
infrared excess this could be well explained as an equal-mass binary
composed of late-type stars of masses ~0.70 Msun (spectral type ~K4).
Total mass of B is 3.6 Msun. Torres estimates the Bab,Bc semi-major
axis at about 83.6 mas and the magnitude difference dV~3.3mag

This system, first announced in Mason et al. but considered of Msn1993a
uncertain veracity, has been included. While its status is not
definitive, subsequent confirmation or suspected duplicity (by another
technique) makes the discovery measurement somewhat more probable.
1991.8995: This is a particularly unexpected result, given the four
previous epochs at which our observations have shown no indications of
duplicity. All four of the earlier observations were reanalyzed using
the same procedures employed here, but no additional supporting
evidence of duplicity was found. If this additional component is
confirmed, vB 41 will be the second K0 giant binary that has been
resolved in the Hyades (HR 1411 being the other). The common proper
motion companion at a separation of 195".5 is far outside our window

04478+3643 GAA 2 AW Per. This Cepheid is an SB with an orbital period of ~40 yr. First
discovered by Miller & Preston (1964 PASP 76, 47), it took several
years to derive the first orbit from radial velocity data (Evans 1989
AJ 97, 1737). It is likely that this companion is itself a binary, as
argued by Evans and by Evans et al. (2000 AJ 120, 407), because the
magnitude difference between the Cepheid and its companion is not
consistent with equal masses and predictions from evolutionary tracks.
Unfortunately, Gallenne et al. (2015) note they did not have enough
angular resolution and sensitivity to detect this third companion. The
properties of the brightest companion were studied based on IUE
spectra by Evans (1994 ApJ 436, 273; 1995 ApJ 445, 393), who found its
spectral type to be B8.3V. This is in agreement with their detection
with a flux ratio f = 1.22 +/- 0.30%, i.e., a spectral type in the
range B6-B9V (using d = 853 pc from a P-L relation and K = 4.63 mag .
for the Cepheid). They estimate the companion mH = 9.6 +/- 0.3 mag .

Monson & Pierce (2011 ApJS 193, 12). Massa & Evans (2008 MNRAS 383,
139) also determined the angular separation of the component for
another epoch, which will allow an estimate all the orbital elements,
(see also Gallenne et al. 2013 EAS Pub. Ser. 64, 197). Gallenne et al.
(2015) derived a maximum sensitivity limit at 3sigma of 0.62%, i.e.,

05074+1839 A 3010 104 Tau.
Two orbit solutions (Eggen 1956). Observations of this close pair Egg1956
are so scattered that both orbits are highly conjectural.
A measure on 1977.9196 was incorrectly attributed to ADS 3701 in
McAlister & Hendry (1982); it actually belongs to ADS 4020. McA1982b
Visual and speckle observations at 0".1 sep ruled out as spurious by
constant RV (Duquennoy & Mayor 1991). Duq1991
Precise velocities are stable to better than 100 m/s over 388 days, Nid2002
so there are no "hot jupiters" and a 2-year period is excluded with Tok2010b
high confidence.
104 Tau is a G4V dwarf at 16 pc resolved into equal components at 0.1"
by R. Aitken in 1912. The WDS contains 16 resolutions of this pair. A__1927a
Apart from Aitken himself, it has been resolved on multiple occasions
by R.H. Wilson in 1934-1971, by W. Finsen (1953-1955) and by others, WRH1941a
although in other instances those observers found it to be single. Fin1953d
The measures suggest a near-circular orbit seen face-on with a semi-
major axis on the order of 0.1" or 1.5 au. Assuming a mass sum of 2
Msun, the orbital period should be around 1.3 yr; in fact, two orbits
with periods 1.19 yr and 2.38 yr were published by Eggen (1956). This Egg1956
binary should be an easy target for speckle interferometry at 4-m
telescopes. It was observed 10 times from 1976.9 to 1980.7 with
speckle and, surprisingly, found unresolved on all occasions,
excluding any short-period orbits. Later, however, two measures were
made by the author at a 1-m telescope with a phase-grating
interferometer. The first resolution in 1984.8 at 0.04" was tentative Tok1985
(below the diffraction limit), but the second in 1985.7 was secure, Tok1988
being an average of two observations. It was followed by the speckle
resolution at 4-m telescope in 1988.17, after which the pair Mca1993
disappeared again. It was found unresolved in 2012. Tok2012b
The star is well studied. Two statistical surveys of binaries within
25 pc consider it to be single (Duquennoy & Mayor 1991; Raghavan et Duq1991
al. 2010). Heintz & Borgman (1984) state that measures cannot be Rag2010
fitted by any orbit and conclude: "Although this alleged visual binary Hei1984i
(ADS 3701) has three published orbits, it is probably spurious".
Several independent RV studies have shown that this star is not a
spectroscopic binary. Precise RVs measured by Nidever et al. (2002) Nid2002
are stable to better than 100 m s-1 over 388 days, excluding orbital
periods from one to two years with high confidence. Data with lower
precision show a constant RV of +21 km/s over many years (Duquennoy &
Mayor 1991; Abt & Willmarth 2006; Raghavan et al. 2010). The star is AbH2006
located about 1m above the main sequence, supporting the thesis of an
equal-component binary. If the orbit is seen face-on, the RV variation
would be small, especially if the components are of equal brightness
(blended lines move in opposite directions, the centroid stays
constant). However, the lines in this star remain narrow and the
speckle non-resolution during 3.8 yr firmly excludes a face-on orbit.
Remember that 104 Tau is bright (no identification errors possible)
and that the components are supposedly equally bright, hence easy to
resolve by speckle. If this star is single (as everything seems to
suggest), we cannot dismiss its multiple resolutions with micrometer,
eyepiece interferometer, and speckle as spurious; occasional image
doubling (or at least elongation) must be real. Tok2012b

Pourbaix gives combined solution for this resolved SB2, yielding Pbx2000b
orbital parallaxes and component masses.
Branham (2008) derives combined interferometric/spectroscopic orbit, Bnh2008
using a semidefinite programming technique. The resulting masses are
3.049 +/- 0.513 and 2.569 +/- 0.432 Msun; he also determines a value
for the parallax of 74.85 +/- 1.53 mas.
Aa,Ab: Following an extensive review of historical spectroscopic and
astrometric measurements of Capella, Torres et al. (2009) derived a Trr2009
new combined-solution orbit, assuming a circular orbit. They determined
an orbital parallax of 76.67 +/- 0.17 mas (distance 13.042 +/-
0.028 pc), an age of 540-590 Myr, and the following physical
parameters for the two components:

Aa,Ab: Weber & Strassmeier (2011) derived new spectroscopic elements, WbS2011
assuming the period determined by Torres et al. (2009). The new Trr2009
solution yielded masses of 2.573 +/- 0.009 and 2.488 +/- 0.008 Msun.
Aa,Ab: A combined solution by Torres et al (2015) yields the following Trr2015

05247+6323 STF 677 AB: CfA: RV var? Can be a sub-system in A or B. Tok2014d
Now a 3 tier quadruple system since we resolved the secondary
component of the binary STF 677AB into a new 0".18 pair Ba,Bb and
confirmed that the Robo-AO tertiary C at 7" is physical. We find C to
be slightly below the MS, within errors. Although the relative motion
of AC is fast, it is not directed away from PM(A) as would be the case
for a distant background star; it is produced by the orbital motion of
the inner binary AB. The presence of an inner subsystem in the binary
AB was suspected previously from its variable RV (Nordstrom et al.
2004). The estimated masses of Ba and Bb, 0.98 and 0.65 Msun, Nrd2004
respectively, remove the discrepancy between the mass sum of 3.05 Msun
calculated for the AB system from its grade 4 orbit by Hartkopf et al. Hrt2008
(2008) and the expected mass sum. Although such discrepancies are not
uncommon for low-quality orbits, in this case it serves as an indirect
confirmation of Ba,Bb. Estimated period of Ba,Bb is ~20 yr. Rbr2015d

05287-6527 RST 137 The primary is AB Dor, a rapidly rotating, spotted star which shows
both X-ray flares and microwave emission.
CLO 10 Aa,Ab: Close et al. discovered a companion to the A component at a Clo2005
separation of 0".156, which they refer to as the A and C components
(the companion was labelled as C when detected as an astrometric
reflex motion of AB Dor in observations by VLBI and Hipparcos).
Based on the astrometric orbit and the AO resolution, the mass of the
Ab companion is estimated at 0.090 +/- 0.005 Msun, just above the mass
of a brown dwarf. AO spectroscopy yields a spectral type of M8 +/- 1.
Mass of Aa & Ab = 0.90(0.08) & 0.090(0.008) \msun. Model comparison Azu2017
gives age of Aa & Ab = 40-50 Myr & 25-120 Myr.

Spectral types of Ba and Bb are estimated by Janson et al. at M5 and Jnn2007

Aa is a rapidly-rotating spotted star (0.09 mag variability in V). Boc2008
Close et al. (2007) find spectral types for Aa, Ab, Ba, and Bb of K1, Clo2007b

and the distance 14.9 +/- 0.1 pc.
Ba,Bb: Wolter et al. (2014) made a multiwavelength study of AB Dor
Ba,Bb. They derive effective temperatures 3260-3360 and 3200-3300K for
Ba and Bb, respectively. Predicted system mass is 0.45-0.71 Msun,
age 50-100 Myr. (Ed note: Inclination for Wolter et al orbit (182deg) WoU2014
appears to be off by 90deg; changed to 92deg in orbit catalog)
Ba,Bb: Azulay et al. (2015) derive an orbit for AB Dor B, yielding a

NOI 1 Aa,Ab: Combined spectroscopic/astrometric solution, using NPOI
interferometric measures with radial velocities from disentangled
spectra to determine first dynamical mass for an O-type supergiant.
Mass of the O9.5Ib primary is 24.8 +/- 5.6 Msun, that of the B0/1
secondary is 16.4 +/- 4.9 Msun. NOI2011
Aa,Ab: Hummel et al. (2013) calculated a combined interferometric/
spectroscopic orbit of zet Ori. Derived masses are 14.0 +/- 2.2 and
7.4 +/- 1.1 Msun; orbital parallax is 3.4 +/- 0.2 mas, but as this is
based on rather low velocity amplitudes, the photometric distance
(2.6 +0.4/-0.3 mas) is considered more robust. Based on photometric
distance, spectral types for Aa, Ab, and B are O9.5Iab, B1IV, and
B0III, respectively. Masses for Aa and Ab are 33 +/- 10 and 14 +/- 3
Msun, considerably larger than the dynamical values. Hmm2013

(1964) astrometric orbit are taken from a revised visual orbit by Osv1964
Alden (cf Osvald's paper); the revised a = 0.254". The different types
of orbits cause the longitude of the node to be in opposite quadrants.

Combined spectroscopic/astrometric solution by Fekel et al. (2002) for Fek2002
the wide pair of this quadruple system, plus spectroscopic orbits for
both short-period pairs. The solution includes mass and distance
determinations.
mu Ori Muterspaugh et al. (2008) combine PHASES astrometry with speckle and Mut2008
radial velocity data to derive an orbit for the AB pair of this
quadruple system, as well as the Aa,Ab and Ba,Bb subsystems. Listed
solution assumes L_Aa > L_Ab and L_Ba > L_Bb; other assumptions result
in some changes of angular elements. The parallax of the system is
determined at 21.69 +/- 0.13 mas (distance 46.11 +/- 0.28 pc), with
semimajor axes for AB; Aa,Ab; and Ba,Bb of 12.620 +/- 0.057, 0.07659
+/- 0.00058, and 0.07780 +/- 0.00036 au, respectively. Other derived
quantities for the four components are as follows:

to determine whether the two components share a common proper motion,

of the components are consistent with expectation, it is likely that

are coincidental. If Bergfors 6 is a binary M dwarf system near

indeterminate because the PM(A) is only 0".053/y and we do not have a

Bessel, in 1834, notes that the proper motion was variable and, in his
letter to Humboldt, stated that "..Procyon and Sirius are genuine
binary systems, each consisting of a visible and an invisible star."
Not quite invisible, this large dm pair consisting of a main sequence
A star and a white dwarf was first resolved by Alvan G. Clark on 31
January 1862 in the process of of testing the 18.5" refractor. See
notes by Burnham and Aitken. Bu_1906
The separation for the 1862.275 measurement by Lassell is reported as Lsl1862
4.92". This is clearly incorrect and not consistent with measurements
by other observers. WDS catalogers assume an factor of 2 error and
correct separation to 9.84".
Otto Struve lists a measurement of Sirius in 1861.21. However, this Stt1893a
predates the discovery of the companion Sirius B by A. Clark and his
son on 1962 Jan 31 and the first formal measurement by G. P. Bond on
1862 February 7. Comparing the uncorrected PA and separation in
Struve's table in 1893 with the measurements published by Struve, we Stt1864
suspect that 1861.21 is a typo and should refer to the observation on
1863-Mar-16.
Companion almost hidden behind secondary mirror diffraction ray from
Sirius B was never observed at these position angles until the early Sea1882
20th century. We suspect that this is a clerical error and that the
measurements pertain to another system.
For the 1882.988 measurement the PA is listed as 41.6 deg and is Bu_1883
40.6 in another. Bu_1883b
Many of the recovery observations of Sirius B following the periastron
passage after 1890 are doubtful. The recovery observations made by See1896d
See, Douglass, and Cogshall at Lowell Observatory from 1896.668 to Dgl1896
1896.695 were taken in the morning shortly before sunrise when Sirius Cog1896a
was low in the sky. See notes that the mean position angle of 220 deg

sep is larger than expected based on previous orbit fit. Aitken and A__1896d
Schaeberle reported measurements between 1896.814-1897.027 made from Shb1897a
Lick Observatory at a significantly different mean position angle of
189 deg and 3.7". Both Aitken and Schaeberle comment that neither of
them saw a star at the position reported by Dr. See. Following the
contradictory reports, Stimson J. Brown published observations from Brs1896
his logbook that were taken earlier in March 1896 at the USNO. The
position angle is similar to the values reported by Aitken, but the
separation is about 1" larger. Brown notes that the observations were
taken under challenging conditions and he did not have much confidence
in their reliability. See later refuted his earlier measurements See1897e
after unsuccessfully searching for the companion while observing from
Mexico and then successfully detecting the companion at a pa of 175 deg
and 4.6" in September 1897 at Lowell. He writes, "The erroneous
conclusion to which I was led last year seems to have arisen from a
very unusual and entirely unexpected cause, of which we need not
speak here..." In hindsight, See also reported in that publication,
two observations from April 1895 that he initially did not think were
worthy of announcing. The difficulty in attempting to find Sirius B
using the Lick Observatory 36 inch in February and March of 1896 was
described by William J. Hussey. Hu_1896
See1900d and Brs1900b measures : "All of the observations have been See1900d
thoroughly checked. A number of errors were discovered in the earlier Brs1900b
reductions and corrected. These reductions have also been slighty See1911
changed by the adoption of a later and better determined value of a Brs1911a
revolution of the micrometer screw. This will account for small
discrepanacies between the results published here and those previously
published in the astronomical periodicals."
For the 1904.186 measuremment by T. Lewis, the title of the article, L__1904
text, and first page of the data table all refer to observations taken
in 1904. Subsequent pages of the data table (including the page that
Sirius is listed on) list an epoch of 1903. However, this is probably a
typo, so date corrected the date to be in 1904.

Finsen. Other observers fail to confirm duplicity of B. Single 1945, B__1929a
1946, 1949, 1950. Recovered by Popovic in 1975 at approximately the Fin1929a
the same position as the 1929 resolutions. If these are periodic, the Pop1977b
next approximate time for resolution is 2020. Therefore, since we
believe the detections of C to be real, but likely of a background
optical interloper, BC carries a "U" code and not an "X" code.
However, very compelling argument that this is a chance allignment of Lec2000
a non-physical background star appearing close to Sirius AB is the
1920-30 time period is now assumed.
Time displacement residuals over a period of 6.8y are linear ruling Ldb1973
out a 6.4y perturbation with an amplitude of 0.14". There is no
evidence of a close companion with this nature associated with Sirius.
Otto Struve corrected his measurements for systematic errors by Stt1893a
measuring artificial double stars. He provided both the original and
corrected measures of the separation and position angle for the
companion of Sirius. Aitken cautions that the variance of the angles A__1935f
and distances compared with other observers is often larger for
Struve's corrected values. However in the case of Struve's measurements
of the companion of Sirius, Bond et al. mean residuals in the position BdH2017
angle improved when using the corrected values, while the residuals in
separation did not change significantly, so the corrected values are
reported here.
For the photographic observations by Lindenblad, tables are given for Ldb1970
the raw individual measures, while only the mean measures are corrected Ldb1973
for emulsion contraction. The average time span covered by these mean
measures is ~ 70 nights, so we used Lindenblad's tabulated scale BdH2017
corrections to compute corrected separations and position angles for
the individual measurements. We then took the mean for plates taken on
the same night, reducing the number of individual measurements from 157
down to 77 measurements on unique dates.

Estimated spectral types are M4.5 and M6.5.
GJ 3417 = LHS 1885. If taken at face value, the body of astrometric
points that exists for this target does not make sense. Three epochs
of astrometry exists: One from Henry et al. (1997) taken in 1996 (rho Hen1997
= 2.0" and theta = 220deg), one from Law et al. (2008) taken in 2005 Law2008
(rho = 1.5" and theta = 320deg), and our data point taken in 2012 (rho
= 1.4" and theta = 240deg). Given that background objects can be
firmly excluded, this would imply an enormously fast orbital motion
since the binary would move from 220deg to 320deg and then back to
240deg within 16 years, which is impossible for such a low-mass binary
with a ∼17 au semi-major axis. However, the astometry becomes entirely .
sensible in an orbital motion framework if we impose a 90deg phase
shift on the Law et al. (2008) position angle such that it is 230deg
instead, giving a continous motion of 20deg in 16 years. In Janson et
al. (2012), we suggested an equal phase shift for similar reasons for Jnn2012

06587-2022 BRG 23 Out of the targets that have been classified as "undetermined" with
respect to common proper motion, the 2MASS J06583980-2021526AB pair is
one out of two that have reasonable (or even large) chances of being
chance alignments rather than physical pairs. The fainter C and D
candidates at larger separations reported in Bergfors et al. (2010) Brg2010
are clearly identified as background contaminants here, given both the
colors and proper motions. However, the B component gives conflicting
information. On the one hand, its brightness and color are fully
consistent with it being an almost equal-mass companion to the
primary, which would be a very unusual coincidence for a background
object, especially at a separation of only 1.4". On the other hand,
from an astrometric viewpoint, the B component is fully consistent
with the expectation for a background object. The deviation from the
background expectation is 0.4 sigma, and the B component has moved to
a position that is 7.4 times closer to the background expectation than
its first-epoch position, with confidence for the motion of 7.5 sigma.
This is also unlikely to happen by chance, hence the evidence is
divergent. Since the magnitude of motion is not inconsistent with what
could be expected for orbital motion of a real physical pair, we keep
it as binary in our analysis, but we note that further observations
will be necessary in order to resolve this issue satisfactorily. Jnn2012

Adaptive optics imaging by Shenoy et al. (2013) in Ks, L', and M bands
suggest the brightness of the "Southwest Clump" (~1.5" from central

Lower mass limit for this feature is 5 x 10^-3 to 2.5 x 10^-2 Msun,
depending on assumed gas-to-dust ratio. Presence of clump with no

TOK 392 Da,Db: This is a quadruple system. The 7".7 AB pair (STF 1102) is
HIP 36485, the CPM component D = HIP 36497 = HD 59450 is located at
112" from it, while the WDS components C and E are optical. The
physical nature of AD is established by common PM, distance, and RV.
D is a known SB1 with P=2708d=7.4yr (Halbwachs et al. 2012, MNRAS 422,
14) and an estimated semi-major axis of 93mas, also an acceleration
binary. We resolved the Da,Db pair at 0".11, dI=2.6. The minimum mass
of Db derived from its SB orbit is 0.27 Msun, while we estimate the
masses of Da and Db as 1.05 and 0.6 Msun from their luminosity. A
previous non-resolution of D is reported in INT4; it was also RAO2015
unresolved with Robo-AO (Riddle et al. 2015). Tok2015c

Quadruple. The two close pairs are separated by 103". The G107-070
orbit depends upon elongations of blended photographic images. While
Harrington et al. (1981) do not determine a value for the semimajor Hrr1981
axis for the close pair, they do determine a period (0.94y), masses of
individual components (0.17 and 0.08 Msun), and distance to the system
(parallax = 0."0896). Application of Kepler's Law yields a = 0."054.
This agrees well with the statement in Harrington et al. that "The
mean separation of the double would be of order 0.05 arcseconds".

period of 70d (double-lined, also detected by GCS, mass ratio 0.7) and
an outer period of 2007d or 5.5yr. The outer system is also detected
by astrometric acceleration (Makarov & Kaplan 2005). We resolve it Mkr2005
here at 0".057, dI=2.0, dy=2.5 mag, and see the orbital motion. The
estimated mass of Ab is 0.88 Msun. The semi-major axis of the 70-d
inner binary Aa,Ab is 7mas, so accurate measurements of AB can detect
the sub-motion to determine the orientation of the inner orbit. Tok2015c

07374-3458 FIN 324 f Pup. It was resolved as 0.2" binary FIN 324AB in 1954.31 by Finsen
(1956) using double-slit interferometer at the 0.7 m Innes refractor. Fin1956a
The components were comparable in brightness with dm from 0.3 to 0.6.
Finsen published 7 mean positions resulting from 25 nights (the last
one in 1960.26). His measures show considerable scatter; the motion
looks erratic rather than regular. Finsen could not resolve AB since
1960.29, despite repeated attempts. However, on 1963.305 he found
another companion C at 0.52" with dm =0.8. In fact W. van den Bos saw Fin1964a
both companions earlier and measured AB and AC simultaneously in
1956.2 and 1959.7 (van den Bos 1957, 1961). AC was measured later by B__1957b
R.H. Wilson, Hipparcos, and various speckle interferometers. All B__1961a
speckle observations show no trace of the subsystem AB, except the one
on 1989.305 where B looks doubtful and much fainter than C (McAlister McA1990
1990). No trace of B was seen at SOAR in 2008-2011 (4 speckle runs).
AC follows a Keplerian orbit with 81 yr period (Hartkopf et al. 2012) Hrt2012a
which was slightly corrected here using the latest measure. This
excludes confusion between the companions (i.e. B and C being the same
star). Besides, both were measured concurrently by van den Bos.
The companion B cannot be real. The closest separation of AC is 0.09"
according to the orbit and excludes any sub-system with comparable
separation because such a triple star would be dynamically unstable.
The fact that the orbit of AC is known does not allow us to explain the
apparent non-hierarchical configuration by projection. If B were real,
its orbital period would be on the order of 10 yr (scaling from the
orbit of AC) and it would have shown up in our speckle data. Like 104
Tau, we have here a binary which actually is not binary, but a ghost. Tok2012b

Reid (2001) 2000.287 data from HST WFPC2 . Paper includes mass and age Red2001
estimates, as well as discussion of L dwarf binary frequency and
semimajor axis distribution.
Bouy et al (2004) derive a combined spectroscopic/astrometric solution Boy2004
for this binary L dwarf. Quoted errors are as follows:
P: +2.475/-2.100y, a: +0".030/-0".023, i: +2.5/-3.4deg,
node: +9.9/-14.2deg, T: +0.14/-0.09y, e: +0.08/-0.09,
omega: +5.2/-5.9deg. Semi-major axis given as 2.53 +0.37/-0.28 au.
Angular values in orbit catalog are based on the quoted distance of
12.21 +/- 0.05 pc. The total derived mass is 0.146 +0.016/-0.006 Msun.
HST spectra indicate spectral types L0 +/- 0.5 and L1.5 +/- 0.5; Bouy
et al. determine age range 150-500 Myr, conclude secondary is brown
dwarf with mass in range 0.060 - 0.072 Msun.

2005), SB1 Tok2012b
The bright star a Pup (HD 64440, HR 3080) is known as a spectroscopic
binary. However, examination of the RV data reveals that the orbit by
Parsons (1983 ApJS 53, 553) is only approximate. The binary is
difficult to measure, always close to the diffraction limit and with
dm~3. Instead of the spectroscopic period of 6.99yr, our orbit has
P=7.4y and is still preliminary. More RV coverage is obviously needed. Tok2015c

physical pair. The projected separation is 253 au. The Ba and Bb
(their B and C) components also appear to be co-moving. From narrow-
band photometry of all components, conclude spectral type of Ba is
M7-M8 and that of Bb is L2-L3; masses are 0.089 +/- 0.001 and 0.078
+/- 0.001 Msun for Ba and Bb, assuming a system age of 5 Gyr. Orbital

08095-4720 DUN 65 A: gam 2 Vel. Spectrum WC8+O7.5e, probably the nearest Wolf Rayet.
B: gam 1 Vel. CD-46@3846. Variable, spectrum B1IV.
AB: Both components are spectroscopic binaries.
The AB pair was formerly known as DUN 64.
I 1175 DE: DE is I 1175 (= RST 4878) at 08 09.5 -47 25.
The Hipparcos distance suggests a position in front of the Vel OB2
association (van der Hucht et al. 1997 NewA 2, 245; Schaerer et al.
1997 ApJ 484, L153) at a distance of 258 +41/-31 pc; however, the
Hipparcos distances for the B stars in Vel OB2 (Brandt et al. 1971 ApJ
1623, L99) yield a comparable distance of 317 +/- 42 pc. This is also
consistent with the distance from the resolution of the binary by
Hanbury Brown et al. (1970) of 350 +/- 50 pc. Thus, we have chosen to HBr1970
keep gam 2 Vel as a member of Vel OB2. Classification is from van der
Hucht et al. (1997). The B component was also observed and appeared
to be single. Classifications of the B, C, and D components are from Msn1998a
Hoffleit & Warren (1991). Hof1991
TOK 2 Aa: The primary is a close WR+O binary. Although the pair is
unresolved, VLTI/AMBER observations on 2004.984 over baselines of
46-85m and wavelength range 1950-2170 nm are fit by a binary model
giving a separation of 3.65 +/- 0.06 mas, position angle 72.7 +/- 8.7

assigned the discoverer designation BUP 115 and component designations
AB, AC, and CD. However, the two A components differ in precise
position by some 12.8 arcminutes. They were later assigned different

08250-4246 CHR 226 Ba,Bb: This close companion to RST4888 has been observed on three
occasions, but has shown little movement over a 1.6-year period. The
1989 measurements of the Rossiter pair were originally published by
McAlister et al. (1990) and Hartkopf et al. (1993). Following McA1990
discovery of the close pair in the 1990 data, these 1989 data were Hrt1993
rereduced, resulting in "preconfirmation" of the new component. Hrt1996b
V438 Pup, Algol-type eclipsing binary, P = 4.9350 d. Zas2011
The new pair was initially given component designations Aa,Ab, but
it was uncertain which component of the Rossiter had been split.
Tokovinin et al. (2015) have determined it was the B component, so the Tok2015c

AstraLux measurement with the data from the original discovery as
listed in the WDS. Since there are no error bars quoted, it is
difficult to formally establish physical companionship. However, even
if we assume that the errors are +/-0.5" and +/-5deg, which should be
very conservative, the background hypothesis can still be firmly
excluded with ~5 sigma confidence. We therefore count it as a
confirmed companion. Jnn2012

secondary being a 0".16 pair of equal stars. Hipparcos failed to
recognize the triple nature of this star. The estimated period of BC
is 15yr. The outer pair AB has closed from 0".8 to 0".5 and moved in

diameters of 6.0 +/- 0.5 and 3.3 +/- 0.6 Dsun, larger than would be

More commonly known as EQ Cha, this star appears single in the
AstraLux images, but has most likely been partially resolved as close
binary in previous imaging campaigns (Kohler & Petr-Gotzens 2002; Koh2002
Brandeker et al. 2006). With an angular separation as small as 40 mas Bnk2006
in 2003, it is fully plausible that the companion exists but was too
close to be resolved by AstraLux in 2010. Jnn2012

resolve the star again on twelve occasions till 1968, except one other
tentative measure in 1962. Yet the object was resolved by speckle in Fin1964a
1989.94 at 0.144" and in 2006.18 at 0.123". Despite orbital period of
∼50 yr estimated from projected separation, the sub-system was not
detected in 3 runs at SOAR (2009-2012), while the wider pair AB was

non-resolutions. Possibly another "ghost" which isn't a real binary, Tok2012b

entirely single in our AstraLux data. Although we cannot strictly rule
out that the companion is presently too close to be resolved with
AstraLux (e.g. due to a close to edge-on orbit and unfortunate timing
of the observation), we consider it relevant to regard the possible

Hummel et al. (2001) include data from the Mark III, NPOI, and PTI Hmm2001
interferometers. Dates have been converted from Julian to Besselian;
error ellipses have been converted into quoted rho and theta errors.
The Mark III data were taken with baselines of 28.0 and 31.5 meters,
using 500, 550, and 800nm filters. NPOI data were taken using three
baselines from 19 to 38 meters and in 20 channels from 530 to 850nm.

a period of 1.07d (Barden, AJ 89, 683, 1984). Barden observed three K
stars in his spectra of this system. Fekel (1989, private comm.) has
observed the third component of this system and finds no velocity
changes in excess of +/- 2 km/sec from 12 spectra obtained since 1984.

13.59 +/- 1.58 mas (73.58 +/- 9.68pc). Ma et al. (2016) resolve two MaB2016
close companions, in addition to the HDS companion, and determine some
orbital elements for all three pairs. The Ab companion is likely a
giant planet or brown dwarf, depending on the inclination angle;
mimimum mass is 12.4 +/- 0.7 Mjup. The Ac companion is likely a brown
dwarf; minimum mass 57.7 +/- 3.7 Mjup. The closest companion appears
to be new, so is given the designation MAB 2Aa,Ab. The Ac component
has a separation similar to the unconfirmed companion measured by
Balega et al. (2006) in 2001, so the BAG 23 designation is retained, Bag2006b

between Hipparcos and Tycho-2 proper motions. Two epochs at Keck in
Mar 2011 and Feb 2013 show substantial orbital motion. The system was
unresolved by Subaru in Dec 2011, suggesting the secondary had moved
too close to the primary to be resolved. System is a probable member

FAR 10 AC: In this previously known system, 2MASS J10162867-0520320 is a
spectroscopic binary of two M dwarf components, which is in turn a
visual companion at 3.2" separation from a white dwarf (WD).
Furthermore, the WD is itself a spectral binary, making the system
quadruple, with a demonstrated physical companionship of all four
components (Vennes et al. 1999 ApJ 523, 386). The 3.2" pairing is
easily distinguished in the AstraLux image, but the spectroscopic
pairs remain unresolved. Because the system must primordially have had
a pre-WD primary much more massive than J10162867-0520320 (given that
the main sequence lifetime of an M0 star is longer than the Hubble
time), we do not count it as an M-star binary for any of our
statistical purposes. The binary is listed as having confirmed proper
motion in Table 4, this is based on the result in Vennes et al. and
not our comparison with the astrometric point in the literature; since
no error bars are listed for that point and since we only get rather
marginally significant results if we assume reasonable errors of 0.1"
and 1deg, we do not draw any new conclusions on the basis of such a
comparison. Jnn2012

confirming the Wilson et al. discovery. The mass of B is estimated at

low-mass stellar companion. Additional information was compiled from

The spectroscopic secondary companion is over-massive, most likely a
close pair of M-dwarfs. If so, the new speckle companion at 1".66 with
a period on the order of 500yr makes the system quadruple. The speckle
companion might contribute to the IR excess found by Torres. The

companion was a background object.
LWR 2 This system has been identified as a member of the TW Hya association
(Kastner et al. 1997 Science 277, 67) and is known as TWA 5. It
contains a previously known brown dwarf TWA 5B, first suggested by
Lowrance et al. (1999) and later confirmed by e.g. Brandeker et al. Lwr1999
(2003). The latter also reported the presence of a close companion Bnk2003
TWA 5Ab at 54 mas from the primary, independently detected by
Macintosh et al. (2001). We detect TWA 5B in our AstraLux data, but MBA2001
not TWA 5Ab, which implies that the projected separation was probably
smaller in 2010 than it was in 2000. The orbit of TWA 5Aa/Ab has been
analyzed in detail by Konopacky et al. (2007). Using the orbital Kon2007
parameters that they determine, we deduce that at epoch 2010.11, the
projected separation should be only about 18 mas, which is well
consistent with our non-detection of TWA 5Ab. We use the best-fit
total mass of 0.71Msun for TWA 5Aa/Ab from Konopacky et al. Jnn2012
Kohler et al. (2013) derive new orbits and masses for the young triple

12177-6410 JNN 79 The two targets 2MASS J12173945-6409418 and J12174012-6409389 are
physically bound, as shown by common proper motion analysis. However,
this means that one of the targets likely has an error in the Riaz et
al. (2006) spectral type determination, since J12174012-6409389 is Ria2006
classified as M2 but is fainter than J12174012-6409389, which is
classified as M3.5. The fact that J12174012-6409389 is fainter holds
true both in 2MASS and in the AstraLux images. Both components are
resolved as close binaries with AstraLux, so we consider it a strong
candidate for a quadruple system, with J12173945-6409418A as the
primary. Concerning which spectral type determination is incorrect, we
consider that it is more likely that J12174012-6409389 is mis-
classified, as the flux ratio to the close companion is closer to
unity than in the J12174012-6409389 case. We thus set the spectral
type of J12174012-6409389A to M3+/-1, and determine the other spectral
types on the basis of flux ratios. Component Bb is not visible in the
i' data, but becomes visible in z' thanks to the higher Strehl ratio
and intrinsic brightness of the component. A fifth object is visible
in the field, but its color reveals it to be a likely background star. Jnn2012

Observed parallax corroborates closely the orbital value given by

from the spectroscopic elements. See discussion in Balega et al. Bag1984b

speckle observations.

12349-4538 ZUC 4AB 2MASS J12345629-4538075 is better known as TWA 16. The presence of a
close companion to this star was noted in Zuckerman et al. (2001)
which seems to be consistent with the companion that we detect.
However, since no explicit astrometric information is given in
Zuckerman et al. other than a rough estimation of the separation Zuc2001b
(0.67"), it is not possible to test whether the companion shares a
common proper motion with the primary at this point. The brightness
and color are consistent with a physical companion, hence the system
counts as binary in the statistics. Jnn2012

Msun, distance 24.4 +/- 2.7 pc Law2006
The position angle for this system given in Law et al. (2006) is Law2006
actually 257.0deg, but since the components are fairly similar in
brightness and there is a fake triplet effect, we assume that there
can be a 180deg phase shift present in the Law et al. data (or
alternatively in both of our epochs). The angular motion in our two
AstraLux images is 1.8deg in about 0.5 years. If taken at face value,
the Law et al. data point would imply 198.4deg angular motion in 4.5
years, corresponding to 22deg per half-year, which is an order of
magnitude too large. On the other hand, if we subtract 180deg from the
Law et al. position angle to get 77.0deg, then the angular motion is
2.0deg per half-year, which is perfectly consistent with our
measurements. Hence, we adopt the latter value for our analysis. Jnn2012

2009-11 repeat themselves, hinting at a 20 yr period. However, the Tok2010
measure by Mason et al. in 2006.2 does not fall on the same ellipse Msn2009
and had to be ignored. It could refer to another star, as FIN 368
should have been unresolved at that time according to our preliminary
orbit, which also matches the speckle non-resolution in 1976.3 and the
non-resolutions in 1964-1966 by Finsen. An alternative orbit with P = Fin1965a
10.13 yr and e = 0.9 can also be fitted to the data. The Hipparcos
measure on 1991.25 contradicts speckle interferometry on 1991.39; it HIP1997a
had to be ignored. Nordstrom et al. (1997) noted double lines Nrd1997
broadened by fast axial rotation of 100 km/s and 20 km/s. However,
individual RVs measured by these authors during 1987-1991 (near the
apastron) do not show any systematic behavior that could be related to
the orbit. Continued speckle monitoring will be critical for
confirming the orbit.

13020+4241 JNN 84 The companion to 2MASS J13015919+4241160 is clearly inconsistent with
a background contaminant, but the astrometry is also inconsistent with
a simple orbital motion of B around A - for instance, the separation
decreases from June 2008 to February 2009, but then increases again to
June 2009. This could for instance imply that either A or B is a close
unresolved binary, where the photo-center shifts on a shorter
timescale than that of the AB orbit. Jnn2012

13024-5201 JNN 85 Due to the very compact arrangement of the three components of 2MASS
J13022691-5200507, it is highly probable that this is a physically
bound triple system. Futhermore, the system is conspicuously close to
the close binary J13025257-5201384 both on the sky and in distance (52
versus 59 pc), hence this is a candidate quintuple system. Only one

If physical, this 0".56 pair would presumably have an extremely long B__1957a
period, given the spectral type and large calculated distance of its
primary. The small change in theta seen over 2.75 years is consistent
with this, implying a period of order 500 - 600 years.

Split by Benedetto Castelli. After resolving AD in C__1616
1617 he wrote to his friend, Galileo, to observe the pair, "It's one of C__1617
the beautiful things in the sky and I don't believe that in our pursuit
one could desire better." Galileo measured it in early 1617. See the G__1617
excellent discussion of its discovery in Leos Ondra's July 2004 Sky &
Telescope article, from which Galileo's measure was extracted. It was
independently found double in 1650 by Jean Baptiste Riccioli in Ric1651
Bologna: "There appears to be one star in the middle of the Great
Bear's tail, where there are actually two, as the telescope reveals."
This was also the first to be observed photographically, by John A.
Whipple with the Harvard 15inch on 27 April 1857. According to Aitken,
this was the first observed photographically (G.P. Bond at Harvard A__1935f
College Observatory in 1857 using an 8 second exposure on a collodion BdG1858a
plate), and the first spectroscopic binary discovered (E.C. Pickering Pck1890

(although it is small, 58mas/y) which, together with photometry,
indicates with high probability that it is a physical pair AB
(Tokovinin & Lepine 2012). We targeted the secondary component B and Tok2015c
found it to be a resolved triple. The faint star C, at 0".92 from B,
is itself a close 0".16 pair Ca,Cb. Note that this is a region of the
sky with very high stellar density, raising suspicion that the Ca,Cb
pair might be a random background object. Re-observation of the triple
in 2015 (to be published) shows, however, that it is physical because
the center of C=(Ca,Cb) moves relative to B with a speed of 11mas/y
(or 3km/s), compatible with the expected orbital motion of BC and much
less than the system's PM of 58mas/y. The estimated period of Ca,Cb is

a distance of ~80au. They also resolved the Innes B component into a
70mas pair, which they designate as B and C. However, the C component
designation is already in use for Innes' 30" companion. Also, their B
designation redefines B from the photocenter of the previously
unresolved close stellar pair to one component of that pair. We have
therefore designated the two stars as Ba and Bb, in keeping with our
usual hierarchical designation scheme.

B is a W UMa-type eclipsing binary.
Star B is W UMa-type eclipsing SB2; P = 0.2678 d (Popper 1943; Ppp1943
Binnendijk 1955, AJ 60, 355). The RV of pair B differs by +30 km/s
from that of star A, much more than the visual motion can effect, and
thus does not represent the true mass-center velocity of B. The
eclipsing period undergoes intrinsic changes considerably larger than
a lighttime effect in the orbit AB. Attempts to identify the ascending
node are thus unreliable: Time shifts of light minima suggest the
first quadrant (Plaut), the RV difference the third quadrant (Heintz).
The close approach in the visual orbit in recent years has prevented
continued study of the eclipsing system.

15152+0456 HDS2143 The composite spectrum of this pair is given in the SIMBAD database as
a K0III, and we derive a magnitude difference of approximately 2.5,
which is slightly higher at bluer wavelengths. This suggests that
while the primary is evolved, the secondary is still near the main
sequence, and so a study could be done along the lines of Davidson et Hor2009b
al. (2009) to determine the age and individual masses of the two stars
from the photometry through isochrone fitting. Also, the orbit we
calculate has very high eccentricity, which helps explain why there
were no successful observations of the pair in the late 1990s:
periastron passage was in 1997, with predicted separation of 6 mas. Hor2015b

pair with dI=3.9, indicating a mass ratio of ~0.5 and an orbital
period of ~30yr. Very likely the resolved binary does not match the

slow motion, the pair is likely much wider than it seems, being seen
in projection. The sub-system CHR 50 Aa,Ab was discovered by speckle
interferometry in 1983.42 at 0.20" (McAlister et al. 1987). A total of Mca1987b
four measures are listed, the last one in 2006.19. Curiously, the wide Msn2009
pair AB was measured with speckle at 4-m telescopes several times (in
1985.50, 1989.31, 1991.39) without resolving the sub-system. We Mca1990
measured the AB and found no trace of CHR 50 in three runs at SOAR in Hrt1993
2009-2012. The separation of CHR 50 implies an orbital period of 50 Tok2012b
yr. Yet the few speckle resolutions show a fast motion or a random
scatter. If the sub-system CHR 50 were real, we would expect it to
cause some wobble in the motion of AB, but no such signal is seen. Tok2012b
CHR 50 The measures show a large scatter and there are many observations of Tok2010b
the wider AB without a measure of this close companion. The nature of

15520+4238 BAR 41 Identity of this system is uncertain. The Tycho measure supports TYC2002
identification of AB with 155200.97+423948.7. Aitken notes "Star C is A__1932a
BD+43 2537 (8.2, G5)", which supports identification of C with
155156.23+423905.8. However, Barnard gave magnitudes of AB as 15 and Bar1932A
15.5, which appears to agree with an elongated Aladin image at
155209.22+424127.5 rather than the Tycho pair. CA would in this case
be 45.4deg, 200.3", which could be explained by a typographical error
in his value for rho. Unfortunately, Barnard's original publication
for this measure is unknown.

is closer to the main sequence, but still above it. The Hipparcos
parallax of B, -4.7mas, is obviously wrong, so we assume the parallax
of the primary, 20.7mas. The RV(B) is variable (GCS), and we resolve
it into a 40mas pair with an estimated period on the order of 1yr. The
pair moved by 10deg in a month. Binary motion is the likely cause of

O3V((f*))-3.5V((f+)), secondary O5.5-6V] with P=2.67d, i=49 +/- 5deg,

Aa,Ab: This is a hierarchical triple system known from spectroscopy
(Mahy et al. 2012, A&A 540, A97). The outer pair (Aa,Ab) was first

This system, first announced by McAlister and recalled in a later McA1984b
McAlister paper after repeated attempts at confirmation, has been McA1993
restored. While perhaps still spurious, the subsequent confirmation or
suspected duplicity (by another technique) makes the discovery
measurement somewhat more probable.
16416+1513 USN 2 LHS 3236 = WD1639+153 = NLTT 43383.
Harris et al. (2013) derive a distance of 30.86 +/- 0.25pc (parallax
31.67 +/- 0.25mas), which is larger than the spectroscopically-
determined distance of 21-22pc and yields a nearly normal mass for
this pair. LHS 3236 is a double-degenerate binary, which eliminates
the possibility of a substellar companion. Temperature of both
components are 7700 +/- 60K. Astrometric analysis favors a DA+DA pair,
with mass sum 1.84 +/- 0.03 Msun, while spectroscopic analysis
suggests DA + DC, with a combined mass of 1.68 +/- 0.05 Msun. Age of
the system is about 3.3 Gyr. USN2013b
The Harris et al. orbit finds a photocentric semi-major axis of 4.37
+/- 0.25 mas. Matches to 2008 and 2010 Keck AO observations yield
dilution factors of 23.0 and 22.2, respectively. The mean of these two
dilution factors gives the semimajor axis value of 98.76 +/- 5.65 mas
listed in the Sixth Orbit Catalog.

16555-0820 KUI 75 Wolf 630.
A flare star, V1054 Oph. One of the shortest orbital period, for pairs
resolved first by naked eye. The radial velocities indicate a third
component. The intrinsically very faint star VB 8 (mag 17, 220") is
also a member of the system. There is strong evidence that it is an
astrometric binary. The pair is the large proper-motion star Wolf 630
which forms a multiple system with the SB Wolf 629 (mag.11.7, 72",
sdM4) and VBS 8 (mag. about 18, 221"), so the whole system is probably
a septuple. There is strong evidence that VBS 8 is an astrometric
binary. Eggen suggests that the group is part of a large moving Egg1965b
cluster. He has observed an UV flare on Wolf 630. According to
Soderhjelm, the mass ratio and mass sum require the secondary to be a Sod1999
closer SB. Unuseable HIP solution.

KUI 75AB is also known as Gliese 644 (B is an SB1 star), component C
is Gliese 643, also an SB1 star. Component F is VB 8 and is also known
as Gliese 644C. Och2010
Also known as GJ 644, this is a well-known and much studied triple
system (e.g. Segransan et al. 2000), of which we resolve the wider AB Sgr2000
pair (the secondary is a spectroscopic binary with a 3 day period). In
addition, there are two much wider components known to share a common
proper motion with GJ 644, making the system a likely quintuple. Since
there are so many existing astrometric points of the AB pair in the
literature, we do not give an extensive list in Table 4, but rather
refer the reader to Segransan et al., where there is a full orbital
analysis of the close triple system. Jnn2012

16563-4040 HDS2394 AB: Fullerton (1990) discovered the short-period spectroscopic Ful1990
variation, and subsequently Wiemker (1992 MS Thesis, Georgia State
Univ.) showed that the spectral variations are best explained by the
superposition of a stronger stationary component and a moving
component. Thus, the speckle resolution of this system (aka, CHR 210)
makes clear that this is (at least) a triple consisting of a short-
period SB1 and a distant O star. Msn1998a

literature, including multiplicity surveys with speckle interferometry
and RV (Chini et al. 2012). Owing to the large distance, no detectable Cii2012
orbital motion is expected. Indeed, the AB pair was measured with
HRCam in 2008.5 at the same position as it is now. Those observations

AB + TOK 53Ba,Bb: This is the triple system HIP 84430. We computed
the first orbit of the secondary subsystem Ba,Bb which was discovered
at SOAR in 2009 and has just completed one full revolution since. Its
separation is always close to the diffraction limit. Adopting a mass
sum of 2.6 Msun for Ba,Bb, the resulting dynamical parallax is
7.6+/-1.5mas, while the HIP2 parallax is 4.9+/-0.9mas. The latest
orbit of the outer pair A 2592 AB published in Tokovinin et al. (2014) Tok2014a
does not account for the fact that the speckle measurements at SOAR
refer to A,Ba and not to AB. Here we give a more accurate solution
that uses the positions of AB computed from the measures of A,Ba under
the assumption that Ba and Bb have equal masses. After this correction
and orbit adjustment, the weighted residuals are 4.3mas in separation
and 1.3deg in angle. Interestingly, there were a considerable number
of speckle-interferometry measures of this pair obtained in the 1980's
and 1990's at 4-m telescopes, but none of them recognized the
subsystem Ba,Bb, despite its small dm.
Ignoring the multiplicity, the spectroscopic survey of Guillout et al.
(2009 A&A 504, 829) determined a moderate axial rotation V sin i =
10.8km/s and detected the lithium line of 52.8mA equivalent width
which, together with the X-ray detection by ROSAT (RasTyc 1715-0948),
normally indicates youth. These authors do not mention this star in
particular, but discuss a group of active lithium-rich giants in their
sample, to which this system apparently belongs. Even with the larger
dynamical parallax (instead of the HIP2 parallax), all three resolved
components of HIP 84430 are located above the main sequence in the
color-magnitude diagram. This multiple system is peculiar and merits
further study. Tok2015c

127" separation (common PM, RV, and parallax). The B component = HIP
85326 has a variable RV and an astrometric acceleration which could
hardly be produced by the 1" speckle companion Bb found here, owing to
its long estimated period of ~300yr. It seems that B is triple and the
whole system is quadruple. This companion Bb was not detected in the
previous speckle observations because it is red: dI = 2.4, dy = 4mag;
its color matches a dwarf star at the same distance as the system.

separation implies an orbital period of ~10yr; the estimated masses
are 1.37 and 0.81 Msun. Despite extensive literature (51 references in
SIMBAD), there is no published spectroscopic orbit, while several
high-resolution spectroscopic studies addressed the abundance. Tok2015c
17342-1910 B 1863 AB + TOK 418AC: B 1863 is a known close binary which has been
unexpectedly found to be a triple. The new distant component C is
detectable also in the y filter, but we measured only the inner binary
in y. The star was observed at the Blanco telescope in 2008.5397, and
the pair actually measured then was AC, at 133.8deg, 0".217, dy =3.7.
The inner pair AB with a smaller dm was unresolved in 2008.5, while it
is clearly resolved now. Owing to the large distance from the Sun, we
expect only a slow motion, so even the inner pair observed since 1929
may not yet be ready for computing its first orbit. Tok2015c
17342-5454 TOK 419 HIP 85969 has a variable RV according to the GCS and confirmed by

ISO 5 Our single observation appears to indicate a single star, so we cannot
HDS2480 confirm the reported ISO 5 Aa pair. Nor did we detect the new
Hipparcos Aa,Ac pair, presumably due to the large magnitude difference
(Delta Hp = 3.2). Msn1998a
Classifications of the Ab and Ac components are from Lindroos (1985). Lnd1985
Lindroos also notes a wider "X" component (V = 10.8, separation = 25",
photometric classification = B5 IV) which he claims is physical. This
component is not mentioned in the WDS. Lindroos finds a distance of
1.8 kpc.
SNA 73 Aa1,2: The primary is V1036 Sco, an ellipsoidal variable star. It is
marginally resolved on two PIONIER observations with minimum
separation rho>0.9mas on the first epoch and rho=10mas about one month
later. The known SB2 has an equal mass ration, P=3.36d, and a sin i =
14 Rsun (Stickland et al. 1993; Linder et al. 2007, A&A 474, 193. Stc1993
Given a probably distance of ~1.5kpc, the expected separation of the
spectroscopic pair is <0.2mas, so we probably detected a 3rd fainter
component. Mason et al. (1998) reported three other companions at Msn1998a
0.27", 0.74", and 5.4". We clearly detect the wider pairs, but not
Aa,Ab. The Ab companion may be a spurious detection (possibly due to
the 10mas Aa1,Aa2 pair), or possibly is too faint for AstraLux and
NACO, implying dm > 5mag. Sna2014

The confirmation by Hipparcos may be due to taking as a first solution
the measure by T.J.J. See. It is possible that a grid-step error is See1896c
involved here and an NDAC solution of PA = 275, sep = 0.51", and
dm = 3.2 seems better. However, this would seem to contradict See's Jaw2006b
original estimate of the magnitude of B at 13. It is entirely possible
that See's pair is spurious. Given the small dm and how obvious the
Sco is, this could not possibly be, as has been suggested, HJ 4963.

A family of possible orbital solutions are determined by Romanenko Rmn1994

method of apparent motion parameters and incorporating parallax and

31 Dra. Toyota et al. (2009) monitored the RV of both the A and B
components every 1-2 months between 2003 Mar - 2007 Nov, using a
high-dispersion echelle (precision ~10 m/s). The A component exhibits
a linear trend in RV, with a slope +220 m/s/y. Toyota et al. assert
that these variations are due to an unseen companion. Assuming a
circular orbit, period is estimated at 3200d; minimum mass of the
unseen star ~50 Mjup. Standard deviation of radial velocities for the
B component <40 m/s and velocities show no periodic variation. This
result rejects the association of a planet of mass > 1.8 Mjup Toy2009

17422+3804 RBR 20 Triple system. The Riddle et al. (2015) companion at 2".2 is confirmed RAO2015
as physical by its fixed position and its location on the CMD. The
main star is a double-lined spectroscopic binary with P = 6 yr (D.
Latham 2012, private communication) and estimated semimajor axis of
0".1. Our standard algorithm, fitstars, produced subpar results on
this star and instead we used the deconvolution technique used in
Riddle et al. (2015) to analyze this star. It is resolved here at
0".07. The magnitude difference of Aa,Ab (dK = 2.43) matches the
spectroscopic mass ratio of 0.52 and corresponds to the Ab mass of
0.60 Msun. The orbital motion of Aa,Ab can be followed with AO and
speckle interferometry. Rbr2015d

Note: This system has grown more complex as additional stars orbiting
the Galactic Center have been observed. With the number of companions
now exceeding 170, it has become increasingly difficult to maintain
the usual WDS designation/component scheme. All WDS pairs were
therefore copied to the WDSS (WDS supplemental catalog) in July 2017;
henceforth the standard published designations for Sgr A* companions
will be used for all components.

Triple star. The orbital planes of the B9.5V eclipsing binary and the
more distant companion (per= 99.3 d.) are not coplanar so the orbital
plane of the eclipsing binary shows nodal regression with a period of
68 years. For about one-third of this time, the close binary is
eclipsing, the rest of the time the inclination is too small for
eclipses to occur. The earliest observations of the system in the year
1899 show eclipses; the eclipses stopped about 1918, started again
about 1963, and stopped again in about 1986. Eclipses should start
occurring once again in the year 2030+/-5. (Otero, 1999 AJ 117, 541L).

rays. Trepl et al. identified a soft X-ray excess and 10sec pulsation
which they interpret as the signature of a neutron star in the system.
Our detection is probably an active later-type object, which may
provide an alternaitve explanation to the X-ray excess. Sna2014

determination of Nordstrom et al. (2004 A&A 418, 989), derived masses

However, since he resolved the system successfully in 1946 with the

non-resolution is probably due to bad seeing or ID error. USN2002

18346-2734 I 1026 AB + TOK 422Aa,Ab: HIP 91075 was noted as a double-lined binary by
the GCS (one observation only). The separation of 86mas implies a
period of ~10yr, while the double-lined observation matches the
moderate magnitude difference (estimated masses 1.04 and 0.77 Msun.
The star is an X-ray source, so a future combined orbit could
determine masses for testing evolutionary models of young stars. The
sky around the object is quite crowded; the 9" companion I 1026 is
optical (it moves too fast). Tok2015c

18352+1812 CHR 74 A well-known speckle binary whose first interferometric observations
date from the CHARA speckle program in the mid-1980's, this object
went unobserved from 1996 until the present work. The new data suggest
that nearly half an orbit has been completed since the first speckle
observation. The primary is probably close to an A0V star, and with a
magnitude difference of perhaps 2-2.5, we estimate that the secondary
is an F2V star. This would suggest a mass sum in the range 4-5 Msun,
which is lower than what is implied by the value of P and a we derive,
together with the Hipparcos parallax of 5.04 +/- 0.39 mas. We expect
that the next decade will provide an opportunity to improve upon the
orbit presented here since the separation will be above 0.1 arcsec and
the position angle is expected to cover about 30deg. We encourage
other observers to put this object back on their observing lists for
the next few years. Hor2015b

18439-0649 YSC 133 A first orbit for this system was reported recently in Tokovinin et Tok2015c
al. (2015), but those authors assumed a quadrant flip of one data
point taken by Horch et al. (2008). That was not an unreasonable Hor2008
assumption based on the relatively small magnitude difference, but the
points presented here give support to an "alternate" orbit where no
quadrant flips are needed and the period is about half of that derived
in the earlier calculation. Given the revised Hipparcos parallax of
13.55 +/- 0.43 mas, the new orbit gives a mass sum of 3.5 +/- 1.0Msun,
which is somewhat high for a system of composite spectral type F7, but
with substantial uncertainty at this stage. In contrast, the Tokovinin

pairs of similar position angle, discovered by Finsen with his Fin1953c
eyepiece interferometer. Our 1982 observations (McAlister et al. McA1987b
1987) were made at lower magnification and included all four stars in
the field. The resulting overlapping autocorrelation peaks precluded
measurement of the Aab or Bab pairs directly, but did permit measures
of the AB; Aa,Bb; and Ab,Ba configurations. In later observations
made at higher magnification we observed the A and B components
separately, enabling measurement of Aa,Ab and Ba,Bb but not AB.

18467-0916 JNN 118 The primary star has two candidate companions in the field of view.
The fainter candidate C is most likely a background star, since its
color is entirely inconsistent with a late M-type star. The brighter
candidate B is more uncertain. It's colors are fully consistent with
the brightness contrast to the primary for a physical companion,
implying a spectral type of M5. It is also visible in 2MASS (Skrutskie
et al. 2006 AJ 131, 1163), which enables to perform a rough CPM test.
The test indicates that B is inconsistent with a static background
object, again implying physical companionship. However, the motion is
also poorly consistent with orbitalmotion, with a sky-projected speed
of order 2 au per year - highly unlikely for such a wide and low-mass
binary. This implies either under-estimated uncertainties in the data,
or an unusual astronomical coincidence. With the small separation and
relatively high brightness difference of the candidate companion, it
is just at the detection limit of 2MASS, and is only reliably
detectable in K-band. Perhaps there is a systematic noise component
beyond the quoted astrometric 2MASS error in this circumstance. If all
the data are taken at face value, another possible interpretation is
an unfortunate chance alignment with a local M-dwarf, which has a
signficant proper motion of its own. In any case, due to all these
uncertainties, we tentatively treat the pair as a candidate binary
here, but emphasize that more data is needed to test physical
companionship. Jnn2012

from 271 to 313 pc; masses for the gainer and donor are 12.76 +/- 0.27
and 2.83 +/- 0.18 Msun, respectively.

In addition to the close pair there is also a hot spot with a size of IAU2014b
22-33 solar radii. What is unknown is where the mass is lost and how
much matter is in the jets.

18550+4822 KOI2754 This system hosts a 0.7 Rearth planet candidate with a 1.3 day period
(Burke et al. 2014). Our ARIES observations revealed a companion 2.11 KOI2014a
J mags and 1.65 Ks mags fainter than KOI2754 at a 0".763 separation.
The predicted Kp mag of the companion star is Kp = 15.3 (dKp = 3.0)
if the star is a dwarf and Kp = 15.2 (dKp = 2.9) if the star is a
giant. The companion star was also detected in the WIYN speckle
imaging acquired with DSSI. The companion is 3.12 mag. fainter than
KOI2754 at 692 nm and 2.56 mags fainter at 880 nm. Assuming that the
planet orbits the target star and that all of the light from the
companion is captured in the Kepler aperture, then the planet radius
should be increased by 3% to account for dilution. KOI2754 does not
exhibit a significant source offset during transit. Dre2014

19062+4926 DSG 2 Kepler 296 = KOI-1422. Derived properties for the A and B components
are as follows:
Teff (K) 3740 +/- 130 3440 +/- 75
Radius (Rsun) 0.480 +0.066/-0.087 0.322 +0.060/-0.068
Mass (Msun) 0.498 +0.067/-0.087 0.326 +0.070/-0.079
Using statistical and analytical arguments, Barclay et al. (2015)
conclude that the five transiting planets associated with this pair
orbit the primary star. The two outer planets (Ae and Af) have radii
of 1.53 +/- 0.26 and 1.80 +/- 0.31 Rearth, respectively, and receive
incident stellar fluxes of 1.40 +/- 0.23 and 0.62 +/- 0.10 times that
received from the Sun by the Earth; this level of irradiation places
both planets within or close to the circumstellar habitable zone of
their parent star. Bcy2015

(Batalha et al. 2013). NEXSci also reports a 0.8 Rearth false positive KOI2013a
with a 31.8 day period. We detected a companion 1.3 Ks mags fainter
than KOI2298 at a distance of 1".47. The companion is expected to have
Kp = 15.2 (dKp = 1.4), indicating that contamination may lead to a
significant underestimate of the planet radius. In the simple
approximation that all light from the companion star is captured in
the Kepler aperture, the radius estimate for the planet should be
increased by 13% to account for the dilution if indeed the planet
orbits the target star and the companion has Kp = 14.9. However, the
companion may be the same object identified ~1" away from KOI2298 in a
HIRES guider image. The estimated brightness contrast from the HIRES
image is three mags, which implies companion is red enough that the
dilution correction might be only a 3% change to the planet radius Dre2014

An astrometric orbit was deduced from Hipparcos data by Jancart et al. Jnc2005
(2005). The period derived for the visual orbit matches both the
spectroscopic and astrometric solutions within the uncertainty, and
other orbital parametrs are in reasonable agreement with the Tokovinin
solution. The updated Hipparcos parallax (39.98 +/- 0.73 mas),
combined with the orbit, yields a mass sum of 2.0 +/- 0.3 Msun. The
composite spectral type is K3V; a magnitude difference of 0.8 mags
makes the component spectral types roughly K1V + K4V, which suggests
a mass sum of 1.2-1.5 Msun, accounting for the lower metallicity. Hor2012b

The A component is SB2. Huelamo et al. (2009) find is also eclipsing. Hue2009
V magnitudes of Aa and Ab are 12.29 and 12.84, spectral types M1Ve and
M2:Ve, masses 0.59 +/- 0.03 and 0.54 +/- 0.03 Msun; distance to the
system is 42+/-3 pc. They also conclude AB pair is CPM and that the B
component is a pure-helium DB white dwarf, mass 0.648 Msun, distance
46pc. The age of the triple ~400 Myr.
19372+2920 HJ 1423 The Wilson Aa,Ab, AE, AF, and AG components of 19448+2916 were
previously assigned to this system, but this was a position error on
Wilson's part, leading to the the pairs not being confirmed for many WRH1950a
years. The wider components of Wilson were moved, but retained their
historical component identifiers. The closer Aa,Ab pair had been
independently discovered by Ismailov, so retained its ISM 4Aa,Ab
designation. The problem was noted by Cliff Ashcraft and the correct
system found by James Daley.
FYM 97 A star at ~80deg, 1' from the primary has been inadvertently measured
under the assumption it was Wilson's AG pair, so has been given the FyM2013c

AD: Baranov (1909) measured new companions at (303deg, 29.2", V=7.8) BnW1909
and (343deg, 160.8", V=9.5), in addition to a measure of the AB pair.
The wide pair was added to the WDS as H 2 26AD, but the 29" pair was
apparently ignored. A check on Aladin shows no hint of either of the
new companions. It appears that Baranov may have accidentally merged
his measure of H 6 26 with measures of the nearby pair 19394+1634 =
H N 84. His 29.2" measure agrees with other measures of that pair, and
a star in the field of H N 84 (V=11.9) matches his wide pair.
H 6 26AD has therefore been X-coded. Since the identification with
H N 84 is likely but not definite (and since the 12th magnitude star
near H N 84 appears to be a random field star), Baranov's measures
have not been added. Thanks to Steve Smith and John Nanson for
alerting us to this discrepancy.

AB: 1951.524 : In Hipparcos Catalog, B component is HIP 96569: there
is no such star in the position of HIP 96569 in DSS plates. So, the
measurement of 1991 (realized from Hipparcos) and included in WDS
database probably is not valid. B magnitude uncertain.
1991.521: proper motion of B is DEC 0"012+-0"004 and AR 0"014+-0"009.
AC: 1991.521: Annual proper motion of C is DEC -0"004 and AR -0"0010

No star is near C coordinates. Realized measure for B and D components

resolved this pair, although the measurement near the diffraction
limit is uncertain. There are some unsolved questions, however. Why,
despite the small magnitude difference dy = 1.2 mag, were double lines
not seen? Why, despite the 1-yr period, was the Hipparcos parallax not
strongly affected and the star appears to be on the main sequence? Tok2015c

19414+4851 KOI2813 This system hosts a 1.2 Rearth planet candidate with a 0.7 day period
(Burke et al. 2014). We detected a companion 1.43 J mags and 1.82 Ks KOI2014a
mags fainter than KOI2813 at a separation of 1".04. The predicted Kp
mag of the companion is Kp = 14.8 (dKp = 1.3). In the simple
approximation in which all of the light from the companion star is
captured in the Kepler aperture and the companion orbits the target
star, then the estimated planet radius should be increased by 15% to
correct for the extra light in the aperture. KOI2813 does not exhibit
a significant source offset during transit. Dre2014
19415+3903 KOI2904 This system hosts a 1.2 Rearth planet with a 16.4 day period (Burke et KOI2014a
al 2014). We detected a companion 2.74 J mags and 2.58 Ks mags fainter
than KOI2904 at a separation of 0".68. Using the J-Ks to Kp-Ks color-
color conversion from Howell et al. (2012), we predict that the Kp mag KOI2012a
of the companion is Kp = 15.8 (dKp = 3.1) if the star is a dwarf or
Kp = 15.9 (dKp = 3.2) if the star is a giant. KOI 2904 has also been
observed with speckle imaging using DSSI on WIYN and the companion was
detected with mag differences of 2.83 mag at 692 nm and 2.77 mag at
880 nm. The estimated dilution correction for this system is 3%
assuming that the planet orbits the target star and that all of the
light from the companion is captured in the Kepler aperture. KOI2904

19416+4259 KOI 266 This system contains a 1.6 Rearth planet candidate with a 25.3 day
period and a second 1.8 Rearth planet candidate with a 47.7 day period
(Burke et al. 2014). It was classified by Slawson et al. (2011) as a KOI2014a
detached eclipsing binary with a period of 25.3 days, suggesting that KOI2011a
the 1.6 Rearth planet candidate with the same period might not
actually be a planet. Instead, the observed decrease in flux every
25.3 days might be an eclipsing binary diluted by the light of a
nearby star. Dre2014

AB: A is 16 Cyg. B is BD+50@2848. A premature orbit has been computed.
Statistically the same parallax within the errors would indicate the
components are physical.
A family of possible orbital solutions are determined by Romanenko Rmn1994
(1994), with periods ranging from 124,000 to 451,000 years, using the
method of apparent motion parameters and incorporating parallax and
radial velocity information.
Based on combined astrometry, velocity information, and Hipparcos
parallax, Hauser & Marcy (1999) determine a family of possible orbits, Mrc1999
with periods ranging from 18,200 yr to 1.3 Myr, depending on the
line-of-sight separation between the components. A second family of
possible orbits are determined assuming the C component is physical
with the system.

solutions, based in part on photographic measures obtained at Pulkova
Observatory from 1960 to 2007. Periods range from 209 - 290 centuries.
Based on predicted mass sums from these various orbital elements, the
135-century solution of Hauser & Marcy (1999) appears at present to Mrc1999
give the most realistic results.

position error on Wilson's part leading to the the pairs not being WRH1950a

high proper motion of F and the long time since the previous FI

CPM of the components suggests that this pair could be physical;
however, since the relative motion of the components is larger than
their proper motion, the question of whether they are physically bound

19468+4231 KOI2879 This system was reported to have a 1.4 Rearth planet with a 0.3 day
period (Burke et al. 2014), but this signal has been found to be a KOI2014a
false positive. Our ARIES observations revealed a companion 0.37 J
mags and 0.27 Ks mags fainter than KOI 2879 at a distance of 0".423.
Using the J-Ks to Kp-Ks color-color conversion from Howell et al.
(2012), we predict that the Kp mag of the companion is Kp = 13.8 KOI2012a
(dKp = 1.1) if the star is a dwarf or Kp = 13.9 (dKp = 1.2) if the
star is a giant. If any additional planet candidates are detected
around KOI2879, their radii will need to be increased by roughly 17%
to account for the additional light in the aperture. Dre2014

19537+4504 KOI2421 The system hosts a 0.7 Rearth planet candidate with a 2.3 day orbit
(Batalha et al. 2013). We detected two companions 0.42 and 2.62 Ks KOI2013a
mags fainter than KOI 2421 at separations of 1".12 and 4".0,
respectively. The closer companion is predicted to be Kp = 15.1 (dKp =
0.7), the farther companion Kp = 17.8 (dKp = 3.5). Due to the similar
brightness of the innermost companion and KOI2421, this system will
require a significant dilution correction. If all light from the
innermost companion is captured in the Kepler aperture and the planet
orbits the target star, the planet radius measurement will need to be
increased by 23% to account for dilution. KOI2421 does not exhibit a
large source offset during transit, which lends support to the theory
that the planet candidate orbits the target star, but the system
should be inspected closely to confirm this. Dre2014

20181+4044 CHR 96 Aa,Ab: 1985.8396, 1988.6630, 1989.7061: These new observations were
found from reprocessing unpublished archival data. We are currently McA1993
undertaking a duplicity survey of all bright (V<8) galactic O stars;
this is one of four new binaries found by us so far in this survey. McA1987a
This system is also a known spectroscopic binary, and we are
reanalyzing archival radial velocity data in an attempt to derive
masses via a combined interferometric/spectroscopic orbit (see Gies et Gie1993
al. 1993 for a similar combined solution of the O star 15 Mon).
The estimated period of the speckle binary orbit (CHR 96 Aa) is 31 y.
The orbit quality rating in Table 1 is our own. The system is
currently unresolved with the Mt. Wilson Hooker telescope, but we
continue to observe this target. The brighter star of the speckle
pair is also a 311-day, single-lined spectroscopic binary (McKibben et Bgn1998
al. 1998). The classifications of the C and D components are from Hof1991
Hoffleit & Warren (1991). Msn1998a
Cluster/Main-Sequence fitting determines a cluster distance of Rbr2010b

CHR 96 ten Brummelaar et al. (2011) use a combination of spectroscopic and CIA2011b
CIA 6 astrometric data, including speckle and CHARA Array long-baseline
interferometry, to derive orbits for both the Aa,Ab and Ab1,Ab2 pairs.
Masses for Aa, Ab1, and Ab2 are 21, 23, and 9 Msun, respectively,
effective temperatures are 33, 32.5, and 20 kK.
Distance to Collinder 419 is 1006(+37-34) pc, yielding a mass sum of MzA2019b

the coordinates nor the measure agreed with that pair, so it has been

Although this measure (40.7deg, 3.79") could conceivably be a measure
of OL 80 with a 100deg theta error (expected values are about

discrepancy between the two data sets. The photometry with P3K shows
large magnitude differences (dJ = 2.5 and dK = 2.3), while Robo-AO
detected a binary of equal brightness. The separation between the two
components is fairly small and in the P3K data, the companion lies on
the Airy ring of the primary, which could increase the errors. The
primary is a high PM star, the pair AB is most likely a physical
binary. Additional observations are needed to understand this system. Rbr2015d

AC and AD: Optical pairs, based on study of relative motion of the

A new 2+2 quadruple system. The outer 17" binary HJ 1535 AB has been
known since 1828 (Herschel 1831). If B were a background star, the PM HJ_1831
of A, 0".208/y, would have moved it by 38" in 185 yr. The pair AB is
therefore undoubtedly physical. The discrepant PM of B reported in
the WDS could be caused by the subsystem Ba,Bb discovered here. The A
component has an astrometric subsystem Aa,Ab with P = 3.9 yr (Goldin
& Makarov 2007), confirmed spectroscopically by D. Latham. The B Gln2007
component was tentatively resolved by Robo-AO, but was thought to be
too uncertain to publish in Riddle et al. (2015). Now Ba,Bb is RAO2015
clearly resolved at 0".17. Its estimated period is ~30 yr. The field
is extremely crowded and another faint star E is detected at 12".1
from A by both Robo-AO and PALM-3000. Comparison with 2MASS shows
relative motion opposite to PM(A), so AE is optical. Rbr2015d

20406+1539 HDS2947 New observations of this object indicate that the orbit is eccentric,
and that we observed the system near periastron (and below the
diffraction limit of the DCT). The orbital elements obtained confirm
that picture, yielding a total mass of 3.4 +/- 0.5 Msun. The composite
spectral type is F5 and the system has a magnitude difference of about
1, so that we might suggest that the individual spectral types are F4
and F9. If so, then the total mass would be on the order of 2.5 Msun,
which is about 2 sigma lower than the value implied by the current
orbital elements and the parallax of 13.96 +/- 0.55 mas. However,
because there is only one point near periastron at the moment, the
orbital elements will of course be modified with time. Hor2015b

and 12.79 +/- 0.3 mag for the two components. They also derive an

observations, plus earlier astrometry by Pravdo et al. (2005; measures Prv2005

triple. The inner Aa,Ab pair are equal-mass stars in an orbit of
period 0.795 days and an inclination in the range 74-83deg, which may
indicate coplanarity with the wider orbit. The total mass of the inner
pair is 0.280 +/- 0.010 Msun, that of the B component is 0.063 +/-
0.005 Msun. Absolute magnitudes are determined for all components in
the J-, H-, and K-bands. Data are compared with evolutionary models.

van Maanan notes a common high-proper motion companion located 1'.3 Maa1934
west and 0'.1 south of eps Cyg. The companion (photographic magnitude
~14.8) was found on two plates taken with the Mt. Wilson 60inch over
an interval of 12 years.
1991.8987: This finally confirms the discovery observation of this
component, made in 1983 (McAlister et al 1987). A number of unresolved McA1987b
observations of this very close system, dating from 1979 to 1981, were
published by Hartkopf & McAlister (1984). Hrt1984
A single lined spectroscopic binary with a period of 55 yr yields an Grf1994a
estimated semi-major axis of 1.05", so the companion has only escaped
visual resolution only due to its faintness. MK III measures of the MkT2003
diameter and no loss of coherence rules out companions with dm < 5.7.
It is possible that CHR 100 is an artifact caused by wave-front Tok2010b
distortions in the dome. The star was likely observed near the zenith
and the separation of the putative companion is close to the first
diffraction ring, as typical for such artifacts.

20577+2624 RAO 24 A new 0".6 binary detected by Robo-AO. It was targeted because of its
variable velocity (Nordstrom et al. 2004) and astrometric Nrd2004
acceleration (Makarov & Kaplan 2005). The binary is confirmed here, Mkr2005
helped by the large PM of the primary. Our photometry places B above
the MS. According to Guillout et al. (2009 A&A 504, 829), the target
is young, so its companion could indeed be a PMS star. The object was
already targeted by Metchev & Hillenbrand (2009) in their survey of Met2009
young stars, but the binary was not detected. After learning of our
discovery, Metchev was able to extract a measurement of the star from

21069+3845 STF2758 61 Cyg. According to R.G. Aitken, this was discovered in 1753 by A__1935f
Bradley. Premature orbits have been computed for AB. This is an Bdy1832A
example of a binary known by its common parallax and proper motion
rather than the orbital motion, which has completed approximately
one-sixth of an orbit in the past 200 years. The extremely large
proper motion of this pair has led to some confusion in identification
of others stars measured relative to the primary. Precise epoch-2000
coordinates and UCAC2 catalog cross-identifications are listed below:

An estimated mass has been used by Josties (1981) to compute the Jti1981
otherwise nearly indeterminate orbit; thus the orbit should not be
used to compute the mass. The RV difference from which the ascending
node is inferred is quite small. Various small variations, formerly
suspected in the period range of about 5-10 years, are absent in the
strong photographic coverage of the last decades.

Hopmann orbit rejected from Fourth Orbit Catalog ("P over 4000 years") Wor1983
Apparent typographical error in Hopmann value for semi-major axis Hop1974
(5".909); value of 15".909 appears better. Still unable to match his
orbit with data, however, despite various quadrant flips of angles,
et cetera. A least-squares fit for remaining elements using data
available to Hopmann and fixing P, T, and e at his published values
yields a = 10".03, i = 101.0, Omega = 312.0, and omega = 343.4
This is much better fit by linear solution. Orbit still in 6th Catalog,
but default solution now linear and orbit is rejected. Proper motion
of A and B very different.

This is an example of a system whose earlier long period, low-
eccentricity orbit has been supplanted by a high-eccentricity orbit
of half P due to correct quadrant determination.
The motion causes double spectral lines over part of the orbit, but
the components are indistinguishable in the spectrum as well as
visually. The RV curve gives the elements T, e, and the longitude of
periastron somewhat in variance with those of the visual orbit; cf.

For the visual pair West (1976) computed the elements P, T, e, and Wst1976
longitude of periastron also from the RV's (orbit 3); tentative
elements a, i, and the node were added by Heintz in order to have a
complete listing in the Fourth Orbit Catalog. Since the components are
visually indistinguishable, the quadrant of the ascending node (but
not the longitude of periastron) is arbitrary; with the node chosen as
listed, the close pair would be the eastern component when the visual
pair is at maximum separation.
The pair was long assumed to have a 12 yr period.

there is no obvious companion in this system at an angle of 80deg. The

magnitude. If Espin meant to quote a position angle of 50deg rather

also says "The other stars referred to are 12.5m, 268.2deg:
15.9arcsec; and 12.0m, 145.4deg: 30.9arcsec." These appear to match
the BC, AC, and AE pairs in the HJ 1718 mutiple system. We therefore

This system counts as single in our statistics, even though it appears
to be a triple system in reality. The reason for this is that the A
component was the AstraLux target, and the BC pair at ~7.8" is outside
of the completeness cut-off at 6". Since the BC pair is visible in the
AstraLux images, we can nonetheless analyze it astrometrically. This
pair was first reported by Beuzit et al. (2004) with rho = 0.978" and
theta = 305.8deg. There are no error bars quoted, but if we assume
that the quoted precision in decimal places corresponds to measurement
precision, and adopt errors of 5 mas and 0.5deg, which should be
conservative in that circumstance, we find that common proper motion
can be confirmed at a 76 sigma confidence level. Hence, physical
companionship can be confidently inferred, even if the errors should
be substantially larger than what we have assumed. Jnn2012

A perturbation of the AB orbit (period ~25y) was first noted by Strand Str1942
(1942). The mass of the third star was subsequently estimated at 0.22
Msun by Harrington (1968) and 0.4 Msun by Heintz (1984). Based on Hrr1968
parallax observations, Franz (1958) associated this third star with Hei1984c
the B component, while Heintz favored the A component. Ebersberger & Fnz1958
Weigelt (1979) found a close visual companion to the A component, Ebe1979
while McCarthy et al. (1982) discovered a companion to B in the near Mcy1982b
infrared. Scardia et al (2010) find the astrometry of the McCarthy Sca2010c
companion to be in good agreement with predictions of the perturbation
orbit, so assume this orbit is associated with B.

elements are fixed to those of Duquennoy (1987). Duq1987
BAG 15 Ba,Bb: There is some confusion in the literature as to whether the
close Balega pair is Aa,Ab or Ba,Bb. However, Duquennoy (1987) says Duq1987
the secondary is a 552d SB2 and Horch et al. (2015) have clearly Hor2015
resolved the fainter star into a close pair and derive an orbit using
the Duquennoy SB elements. The components of the close pair have
therefore been changed to Ba,Bb accordingly.
Ba,Bb: For the Horch et al. (2015) combined solution, all elements are
calculated from the speckle data, but a double-lined orbit exists due
to Duquennoy (1987). This orbit has similar elements to the orbit here Duq1987
except for the time of periastron passage. Assigned spectral types
for A, Ba, and Bb are F9V, G5V, and K1V; derived masses are 1.12, 0.92

unknown. At some point during the 20th century, the B and C components
were in approximately the same position, which probably contributed to
the lack of early epoch AC measures. It is possible that some of the

23347+3748 YSC 139 Data at hand suggest that this F8 pair with small magnitude difference
is viewed nearly edge-on. The mass implied by the spectral type is
perhaps 2-2.5 Msun, if the system were to have solar metallicity,
again lower than that implied by the orbital elements. The metallicity
of the system is -0.31 according to the Geneva-Copenhagen Catalog
(Nordstrom et al. 2004), which would tend to lower the mass at a given Nrd2004
spectral type, thus making the discrepancy worse. Nonetheless, given
the large uncertainty in dynamical mass, it is no worse than a 2 sigma
difference at this point. The mass ratio in the Geneva-Copenhagen
catalog is 0.9, so this at least is consistent with the small
magnitude difference obtained from speckle measures. Hor2015b

Aitken notes that Guillaume gives his 1923 measure without Gui1932A
identification and that the other Guillaume measure goes with A__1932a
STT 508AC. The pair was assigned the designation GUI 39, but nothing
matching his separation and angle can be found in the vicinity of STT
508. The GUI 39 designation has therefore been removed, under the
assumption that Guillaume's measure was of STT 508 but there was some

supported by the fact that his angle of 19.5 could instead be 195, in
good agreement with contemporaneous measures of the Struve AB pair, as
well as the match of his wider pair with the Struve AC pair.
