                         A second candidate companion at 39" is noted in UCAC2 as having much            
                         different proper motion, so has been ruled out as a companion. The              
                         measured proper motion of the companion between the two SofI observing          
                         epochs is (+368 +/- 68 mas, -48 +/- 68 mas). IR spectroscopy suggests           
                         a spectral type of M4-M5V for the B component.                          Mug2007b

                         estimated mass for the companion of  69 +/- 20 Mjup. Thus it can no

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

01437+5014   CIA   6     Phi Per. Be+sdO binary, resolved by the CHARA Array. The hot subdwarf           
                         companion is detected in near-IR; flux contribution 1.5% in H (dH=4.6)          
                         and restricted fits indicate flux contribution rises to 3.3% (dV~3.7)

02182+3920   A   207     Scardia et al. (2001) orbit preliminary as all the orbital elements     Sca2001d
                         are still rather uncertain. Hipparcos parallax (0".01200 +/- 0.00311)           
                         seems to be overestimated and leads to a mass sum 0f 0.46 Msun,                 
                         unacceptable for a system of type F5. Scardia (1982) classified the     Sca1982a
                         star as type F9. Dynamical parallax is 0".0065; the corresponding mass          
                         sum is 2.87 Msun.

                         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

                         will certainly change little in the future; only the period is still            
                         slightly uncertain. The Hipparcos parallax is 0".02012 +/- 0.00150.

                         calculated by Scardia in 1980, the total mass of the system, whose      Sca1980e
                         uncertainty was then 55%, is now much better defined. The dynamical

                         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

                         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

03592+8020   JNN  27     A companion to 2MASS J03591438+8020019 was detected on two separate             
                         occasions with AstraLux, in both cases the detection is rather

                         we count it as a genuine detection. However, due to the poor quality            
                         of the fit and the fact that the two epochs of observation are only             
                         separated by 3 months, we do not try to acquire two epochs of

                         This complex multiple system has had numerous identification errors

                         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

                         "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

                         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

                         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

                         uncertain veracity, has been included. While its status is not                  
                         definitive, subsequent confirmation or suspected duplicity (by another

                         1991.8995: This is a particularly unexpected result, given the four

                         evidence of duplicity was found.  If this additional component is

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      .     
                         (using for the Cepheid at theirgiven phase mH = 4.84 +/- 0.01 mag from  .     
                         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.,            
                         dmH> 5.5 mag, so can therefore exclude any additional components with   .

                         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

                         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

                         appear consistent with our estimated period of ~15 or so years;                 
                         however, the magnitude difference between the components is small, so           
                         we are unable to rule out a 180 deg quadrant flip or perhaps an

                         AB was suspected previously from its variable RV (Nordstrom et al.

                         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

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.

06085+1358   STF 848     There has been considerable confusion in component identification for           
                         this complicated multiple. Components K, J, M, O, and Q were actually

                         were actually JR, RS, ST, and SU, respectively. Three CE measures               
                         actually were of JI, while one other was of DH. It is believed (but             
                         not guaranteed!) that components are now identified consistently.

                         sequence star. Relative photometry suggests Bergfors 6 is ~50% closer           
                         to Earth than is WASP-12, and that their consistent radial velocities

                         2012, private communication) has a tertiary companion discovered with           
                         Robo-AO and seen in an archival 2MASS image. This component is located          
                         above the MS, but its photometry has large errors. Its status remains           
                         indeterminate because the PM(A) is only 0".053/y and we do not have a           
                         sufficiently long time base. A wider pair (AB = UC 1450 at 53") was             
                         identified as a common PM pair (Hartkopf et al. 2013), however, the     UC_2013b
                         colors we find here implies it is optical. Crowding is moderate.

                         Bessel, in 1834, notes that the proper motion was variable and, in his          
                         letter to Humboldt, stated that "..Procyon and Sirius are genuine

                         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.

                         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           
                         at 5.10" is about 30 deg behind its predicted location and the sep              
                         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

                         Sirius is listed on) list an epoch of 1903. However, this is probably a         
                         typo, so date corrected the date to be in 1904.

                         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

                         reported here.

                         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

                         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

                         suggest the brightness of the "Southwest Clump" (~1.5" from central             
                         star) is almost entirely due to scattering from silicate dust grains.           
                         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               
                         apparent counterpart on other side of star suggests ejection event.     SDP2013

                         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

08231+2648   BUP 115     The IDS incorrectly associated this pair with BD+28 1598, rather than           
                         +27 1602. As a result, it was initially assumed to be a member of a             
                         quadruple system with two other pairs in the IDS. Eventually all were           
                         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            
                         WDS designations but discoverer and component designations were not             
                         corrected. The AC and CD pairs have now been assigned the designation

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

                         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

08310+4012   SKF 207     For astrometric analysis of 2MASS J08310177+4012115, we compare our             
                         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

08391-5557   HU 1443     A,BC is a triple system. We provide the first very tentative orbit for          
                         the outer binary, but note its large residuals from the recent                  
                         measures of AB. Strictly speaking, the orbit should describe the                
                         motion of the center-of-gravity of BC around A, rather than the

08447-2126   HDS1260     AB + TOK 395: Like WDS 08021-1710, the late-type nearby binary HDS              
                         1260 was discovered by Hipparcos and is expected to move rapidly (HIP           
                         42910, BD-20 2665). It was targeted at SOAR for the first time. To our          
                         surprise, the object turned out to be a resolved triple, with the               
                         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            
                         position angle since its discovery. The separations between components          
                         are comparable, so this triple system may be interesting dynamically.   Tok2015c

10070-7129   TOK 397     HIP 49546 is an astrometric binary of 1.5yr period (Goldin & Makarov            
                         2006) with variable RV. The period corresponds to a semi-major axis of  Gln2006 
                         25mas. The star is resolved here tentatively at 26mas. This resolution          
                         is below the diffraction limit and needs confirmation. The measured             
                         position angle of 346deg is close to 342deg predicted by the                    
                         astrometric orbit.                                                      Tok2015c

             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

                         (Torres 2006), with period 570.98d (1.56yr), K1=20.76 km/s, e=0.611.    Trr2006a
                         The Hipparcos parallax corrected for binary motion is 20.6+/-1.9mas.            
                         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                
                         system is an X-ray source, and is possibly young.                       Tok2015c

                         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

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

                         1989). This is not the SB2 because the observed angular separations     Bte1989 
                         are much larger than the 12 mas maximum predicted by Halbwachs (1981)   HJL1981 
                         from the spectroscopic elements. See discussion in Balega et al.        Bag1984b
                         (1984), who give preliminary orbital elements based entirely on                 
                         speckle observations.                                                           
                         1985.2053, 1985.2491: These measures agree well with the preliminary            
                         orbit of Balega et al. (1984), who adopted a period of 13 years. The            
                         orbit proposed by Tokovinin (1984) with P = 9.8 years fails to fit the  Tok1984

                         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

                         but no pair is found at that location. However, a pair in excellent             
                         agreement with his measure is found at the location of his cross-               
                         reference catalog entry, BD+61 1312.  Apparently there was a 2h error           
                         in Luyten's 1950 coordinates. Given the size of the error, correction

                         a simple orbital motion of B around A - for instance, the separation            
                         decreases from June 2008 to February 2009, but then increases again to

                         J13022691-5200507, it is highly probable that this is a physically              
                         bound triple system. Futhermore, the system is conspicuously close to

                         versus 59 pc), hence this is a candidate quintuple system. Only one

                         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.

                         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

                         (although it is small, 58mas/y) which, together with photometry,

                         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

                         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          
                         ~30 years, the period of BC is ~300 years.                              Tok2015c

                         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

                         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

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

15462-2804   BU  620     The binary companion B discovered by S.W. Burnham in 1878 moved since   Bu_1879 
                         then by +6deg in angle, now at 0.63" separation. Considering this               
                         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           
                         the motion or even the reality of this pair is in question. A "ghost".

                         Spectral types are M4.0 +/- 0.5 and M7.0 +/- 2.0; masses are 0.20

                         projected separation of 15.7 +8.8/-2.5 au. Estimated spectral types

                         In addition to the astrometric points listed in Table 4, there is               
                         another data point from 2005 in Law et al. (2008). This point is        Law2008 
                         essentially at equal epoch to the Daemgen et al. (2007) point, but the  Dae2007 
                         position angle differs by 88deg in the two cases. While the Daemgen et          
                         al. data point is fully consistent with all other astrometric points            
                         of the target, the Law et al. point is fully inconsistent in this               
                         regard. The close to 90deg offset could imply some trivial                      
                         trigonometric error in reduction. Here we simply exclude the point

                         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

                         pair (the secondary is a spectroscopic binary with a 3 day period). In

                         proper motion with GJ 644, making the system a likely quintuple. Since

                         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

                         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

                         also a pre-MS subcomponent to A with a mass of 1.8 +/- 0.2 Msun. The            
                         dynamical parallax is 112 +/- 5 mas, about a factor of two smaller              
                         than the Hipparcos value of 216 +/- 42. The dynamical value is much             
                         more accurate. Two components have calculated effective temperatures            
                         of 25000 +/- 1000 and 21000 +/- 1000 degrees Kelvin, respectively.

                         separation implies an orbital period of ~10yr; the estimated masses

                         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

                         of HJ 2807, however. Burnham says HJ 2807 is "undoubtedly identical     Bu_1906 
                         with STF2190" (= BDS 8082). Herschel's 1830.47 measure was accordingly          
                         reassigned to STF2190. Gauchet disagrees with Burnham, but his          Gau1925 
                         separation does not agree with Herschel's and his coordinates precess           
                         to location of a 7th magnitude star (BD+20@3531) 1.5m east of                   
                         Herschel's. Separation and magnitudes of this pair, designated                  
                         GAU  21, agree with Gauchet's, although the quadrant is reversed.

                         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.

                         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

                         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.

                         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

                         the Galactic Center have been observed. With the number of companions

                         1899 show eclipses; the eclipses stopped about 1918, started again              
                         about 1963, and stopped again in about 1986. Eclipses should start

                         distance of 1 kpc (Trepl et al. 2012, MNRAS 427, 1014). Moreover, the           
                         SB2 has nearly equal masses, while the resolved pair has dH=3.4,

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

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

                         were detected. The B, C, H, I, J, K, L, and M components are unbound;

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

                         which is somewhat high for a system of composite spectral type F7, but          
                         with substantial uncertainty at this stage. In contrast, the Tokovinin          
                         orbit gives a mass sum of about 1 Msun, which would seem to be too low

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

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

                         entry for KOI2159 also includes a 1 Rearth false positive at a period           
                         of 2.4 days. The estimated dilution correction due to the extra light           
                         from the companion is a 3% increase to the planet radius. KOI2159 does          
                         not display a significant source offset during transit.                 Dre2014

19138+4548   KOI2298     This system contains a 1 Rearth planet candidate with a 16.7 day orbit          
                         (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

                         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

                         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

                         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

             LIM   3     Aa,Ab: GJ 779 = 15 Sge. Due to the high proper motion of the primary,           
                         Liu et al. (2002) determine that the faint companion shares common      LiM2002 
                         proper motion. Spectral type of the companion is estimated at L4.5 +/-          
                         1.5; assuming the two components are coeval, the inferred mass of the           
                         companion is 55-78 Mjup.

                         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

                         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           
                         the archival data (S. Metchev 2015, private communication).             Rbr2015d

                         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

                         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

                         regards to common proper motion, but the components have similar                
                         colors and brightnesses, and a relatively small separation of ~0.97"            
                         hence the pair is probably physically bound, and counts as such in the

                         The motion causes double spectral lines over part of the orbit, but

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

                         and it is therefore likely that they form a physical binary pair.               
                         Common proper motion has not yet been demonstrated.                     Jnn2012

22019+5506   HJ 1718     AB: HJ 1719 = STI2607. Burnham's note for HJ 1719 quotes Herschel as    Bu_1906 
                         mentioning "a third star 12m from B, 4arcsec; also a fourth." Burnham           
                         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            
                         conclude that HJ 1719AB and HJ 1718AB are the same pair.

                         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

             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.

                         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

                         The bright primary has a large proper motion along approximately the

                         component B is quite small. The proper motion of component C is                 
                         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            
                         early AB measures may have actually been measures of A,BC. A detailed

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

                         identification and that the other Guillaume measure goes with           A__1932a

                         matching his separation and angle can be found in the vicinity of STT

                         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.
