KISELEV (1922-2013) The Pulkovo Observatory regrets to announce that on September 30, 2013, the famous specialist in astrometry and stellar astronomy and member of IAU Commission 26, Professor Alexei Kiselev died at age of 91. Alexei A. Kiselev was born February 28, 1922 in Petrograd. He headed the study of double and multiple stars as well as stars with invisible companions at the Pulkovo Observatory. Thanks to his efforts the 26-inch refractor of Pulkovo Observatory had been converted into the leading tool among telescopes of the same class around the world. He was the undisputed leader in the number and duration of the regular series of observations of the Solar System bodies and binary stars. His monograph "Theoretical Foundations of Photographic Astrometry" had become required reading for students and researchers specializing in the field of astrometry. Also he is the author of two Pulkovo catalogs of double star positions. In addition to the binaries, Prof. Kiselev paid great attention to the study of the Solar System. He was actively involved in the observations of the satellites of Mars and Halley's Comet at the Pulkovo South Ordubad station. For his great contribution to the observation of the minor planets, No. 4592 was named in his honor Alkissia.

A single-epoch follow-up observation at intermediate resolution carried out on 26 August 2012 using the ISIS spectrograph at the William Herschel Telescope on La Palma (Spain) revealed a high heliocentric radial velocity of this star, amounting to −150 km s−1 . J20354703+4053012 is at a projected distance of only 3 from A37, another member of Cygnus OB2 first identified by Comeron et al. (2002, A&A 389, 874) and classified as O5V by Hanson (2003, AJ 597, 957). A37 was found to be a runaway star by Kobulnicki et al. (2010, ApJ 710, 549) based on the presence of a clearly delineated bow shock ahead of it revealed by Spitzer images, caused by the interaction between the stellar wind and the interstellar medium as A37 moves supersonically through the latter. The angular proximity between both stars and the high radial velocity of J20354703+4053012 raise the possibility that both J20354703+4053012 and A37 may be former members of a multiple system, expelled from it in relatively recent times given their proximity on the sky. Observations of J20354703+4053012 were carried out in September and October 2013 using the TWIN spectrograph at the 3.5m telescope on Calar Alto, with the goal of discerning between a runaway origin of the high radial velocity and the alternative possibility of spectroscopic binarity. The results conclusively show that J20354703+4053012 is a spectroscopic binary, with measured radial velocities of −100 km s−1 on 19 September 2013 and +50 km s−1 on 8 October 2013, based on photospheric lines in the 400 nm to 500 nm interval. A third spectrum obtained on 14 October using a grating setting that covers only the H-alpha line yields a radial velocity of −50 km s−1 , albeit at lower accuracy. Hints of a secondary star spectrum are seen in the shapes of the Balmer absorption lines, which show asymmetric wings extending redward when the center of the line is blueshifted, and blueward when the center is redshifted. The limited number of epochs available suggests an orbital period around one month, and the detectability of the secondary star spectrum in the form of Balmer lines asymmetries suggest that its spectral type is probably around mid-B. Having reached the main goal of discarding the runaway nature of J20354703+4053012, the authors do not have any further follow-up observations of this system planned. With this note the authors want to encourage other teams to carry out new observations for the goal of determining the accurate orbital parameters of the binary system. F. Comeron ^1 , A.

Most entries in the WDS and other USNO double star catalogs are extracted from papers discovered through our literature searches. Although we include data from over 8,300 references at present, we are undoubtedly missing many others! If you wish to check whether your papers (or those of your colleagues) have been entered, you may check the WDS reference file at http://ad.usno.navy.mil/wds/Webtextfiles/wdsnewref.txt (or send a note to wds[at]usno.navy.mil and we'll hunt for you). If you know of missing papers or errors, please tell us (or better yet, send the data files). If you want to be sure that your latest astrometry, photometry, or orbital/linear elements are added more quickly, you may send us text versions of your tables (after your paper is in press or published, of course). Finally, if you have spectroscopic elements not yet in SB9, we're sure Dimitri Pourbaix would love to hear from you! William I. Hartkopf & Brian D.

Quand son pere lui offre sa premiere lunette, une modeste 61 mm de diametre, il se met assidument a observer le ciel et deja les etoiles doubles exercent sur lui une sorte de fascination. Cependant sa carriere universitaire semble devoir faire de lui un astrophysicien. Licencie en Mathematiques en 1947, et apres deux annees d'enseignement, il entre a l'Institut d'Astrophysique de Paris, ou il a comme Maitre de Recherche Evry SCHATZMAN, specialiste des naines blanches, ce qui explique que la these de doctorat qu'il soutient en 1956 soit consacree a la physique de ces astres. Elle a ete publiee aux Annales d'Astrophysique: "Contribution a la theorie du spectre des naines blanches". Mais entre temps, un poste lui est propose a l'Observatoire de Nice, avec pour mission l'etude et la recherche des etoiles doubles visuelles. Des son arrivee en janvier 1951, il organise l'observation de ces astres a l'equatorial de 38cm. Il a a son exclusive disposition une de ces quatre fameuses lunettes francaises de 38cm, celle de l'Observatoire de Nice avec laquelle il se sent le "Maitre de l'Univers". Pendant une dizaine d'annees, Paul COUTEAU mesure les etoiles doubles. Mais petit a petit, l'idee de faire une prospection se fait jour a la suite d'une douzaine de decouvertes fortuites et spectaculaires, comme COU 14 trouvee le 19 novembre 1959, devenue depuis tres celebre par la velocite du compagnon pour effectuer une revolution en moins de 26 ans, ce qui a permis de calculer l'orbite et la masse de ces deux etoiles, but premier de ces observations. Aujourd'hui, Paul COUTEAU voit le compagnon terminer sa deuxieme revolution autour de la principale. Mais pour decouvrir des etoiles plus serrees, qui tournent plus vite, et calculer des masses plus rapidement, il faut beneficier d'instruments plus puissants, de plus grand diametre. L'envie de lunettes plus puissantes devient une obsession. Celle de 76cm de Nice, a deux pas du 38cm semble l'attendre, elle est laissee a l'abandon depuis 1926. A la suite d'un sejour a l'Observatoire de Paris il obtient un objectif de 52cm pour remplacer le 38cm, et en janvier 1967 il est essaye sur le ciel. C'est egalement a cette epoque qu'il fait restaurer le grand equatorial de 76cm. Dote de ces instruments perfor- mants, Paul COUTEAU divise ses nuits en deux parties: d'abord la recherche de couples nouveaux a la lunette de 52cm tres maniable (120 pointes a l'heure), puis avec la grande lunette de 76cm, l'observation de binaires en phase cruciale, tres serrees, dont l'orbite semble se dessiner. Il fait une moisson d'etoiles doubles digne des chercheurs Americains du debut du XXe siecle. Il est souvent invite par des astronomes etrangers. Il effectue de nombreuses missions aux lunettes de Lick et de Yerkes (91cm et 102cm de diametre) et au telescope du McDonald (91cm) aux etats-Unis, au telescope de 152cm de Calar Alto en Espagne, et tres souvent au telescope Bernard Lyot de 200 cm du Pic du Midi de Bigorre en France, ou il est un des rares astronomes a mettre l'oeil a l'oculaire, pour observer "ses cheres binaires" jusqu'au pouvoir separateur de cet instrument. Paul COUTEAU a visite 180 000 etoiles environ, effectue pres de 28 000 mesures et decouvert plus de 2 700 couples pour la plupart tres serres et qui, deja, fournissent un nombre important d'orbites et de masses, but essentiel de l'observation des etoiles doubles. Plus de 80 orbites ont ete calculees, plus de la moitie ont fait l'objet de publications dans les revues specialisees internationales. La prospection des zones celestes choisies, de la declinaison +17deg a +52deg, est complete a 96% et s'est arretee en 1992. Toutes les observations, y compris le reperage et les identifications multiples de tous les couples COU sont conservees soigneusement au Centre des etoiles Doubles de Nice. A ce travail gigantesque, minutieux et fatigant, exigeant une acuite visuelle et une habilite peu communes, d'autant plus que tous ces couples doivent etre mesures et remesures a maintes reprises, il faut ajouter le calcul de dizaines d'orbites, nombre d'etudes theoriques, la constitution d'un fichier, commence en 1956, qui rassemble 25 000 binaires avec toutes les mesures constamment mises a jour. Aujourd'hui ce fichier, appele SIDONIE (Systeme Informatique des DOubles de NIcE) est informatise et disponible par internet (http//:sidonie.obs-nice.fr). Paul Rene Gilles COUTEAU est ne le lundi 31 decembre 1923 a La Roche sur Yon en Vendee, France. Il nous a quitte le jeudi 28 aout 2014 a 11h20 TL a l'hopital prive geriatrique Les Sources a Nice, France Il a ete inhume le lundi 1er septembre 2014 a Chantonnay (F-85110) en Vendee, dans le caveau familial. De nombreux amis et eleves reconnaissants lui gardent le souvenir respectueux et affectueux. Nice le 15 septembre 2014 Jean-Claude THOREL ------------------------------------------------------------------------------------------ IN MEMORIAM OF DR. PAUL COUTEAU We received notice of the passing of our colleague and friend, Paul Couteau, with profound sadness. He was a benefactor of our Observatory and facilitated our observation campaigns in both Nice and Pic du Midi (1986-1999). Moreover, Dr. Couteau was especially supportive of our research team. Proof of that was the hospitality that he demonstrated to Dr. Ling during her research visit in Nice in 1986, his assistance with the construction of our thread micrometer, his participation in our first observation run in Calar Alto, and by serving as a member of the dissertation committee of J. F. Ling, among other things. He had complete confidence in Professor Docobo to whom he assigned the responsibility of editing the Information Circular of our Commission 26 in 1993. This distinguished figure of Astronomy was an excellent observer who discovered more than 2,700 binaries and was the creator of the European Center of Double Stars at the Nice Observatory, among many other outstanding professional activities. May he rest in peace. J.A. Docobo & J.F. Ling R.M. Aller Observatory ------------------------------------------------------------------------------------------ JEAN C.A. DOMMANGET (1924-2014) The Royal Observatory of Belgium regrets to announce that Dr. Jean Dommanget, honorary Head of the Department of Astrometry and Celestial Mechanics, died on October 1st, 2014, at the age of 90 years. Jean Dommanget was born in Brussels (Ixelles) on June 13th, 1924. He started to work at the Royal Observatory of Belgium as a temporary aid in the Section of Double Stars headed by Dr. Sylvain Arend in 1947. While already employed, he studied further and obtained a university degree in Mathematical Sciences (1950), and a Ph.D. degree (1961). Since 1961, he was a member of the I.A.U. Commission 26 "Double Stars". Author of many different publications during his long career at the Royal Observatory, Jean Dommanget worked in various fields including the astrometry and dynamics of visual double stars, stellar occultations and the lunar profile, studies on the atmospheric turbulence, asteroids, solar and lunar eclipses, mathematical tools, orbital properties and stellar evolution of binary stars. He also contributed to some important steps in the development of modern European astronomy. In 1955-57, he conducted a 1.5-yr prospection mission in South-Africa in order to help find a suitable site for the construction of a new European observatory (European Southern Observatory - E.S.O.). He later returned to take on the position of Director a.i. of the Boyden Observatory in Bloemfontein, South Africa. From 1967 till 1973, he was successively Vice-President and President of Commission 26. In 1981, he joined the Input Catalogue Consortium (INCA) of the European Space Agency's astrometric mission, Hipparcos, under the leadership of Dr. C. Turon where he headed the sub-group "Double Stars" of the Executive Committee. At the request of Dr. M. Perryman, leading scientist of the Hipparcos mission, he joined the Double Star Working Group in 1993. In particular, with the expert help of his assistant, Mr. O. Nys, he developed a new double star catalogue known as the "Catalogue des Composantes d'etoiles Doubles et Multiples" (C.C.D.M.) with one entry per component adapted to the needs of the Hipparcos Input Catalogue (HIC). The compilation of the C.C.D.M., based on the Index Catalogue of Double Stars (epoch 1976.5), took many years, and a 1st edition was published in 1994. He furthermore contributed to the publication of the Hipparcos Catalogue, Annex 1 - Double and Multiple Stars (ESA 1997, Vol. 6). Among his main achievements, his continuous efforts regarding the inventory of the visual double stars for the Hipparcos space mission will no doubt be remembered for many years to come. Primarily, he will be remembered as an expert in the field of classical double-star astronomy.
