                                ALEXEI A. 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.

                        NEW SPECTROSCOPIC BINARY J20354703+4053012
 
The star J20354703+4053012 (magnitude B = 13.8) was reported as a likely new member of the 
Cygnus OB2 association by Comeron & Pasquali (2012, A&A 543, 101), who classified it as 
B2V using low-resolution spectroscopy in the blue. 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.

                         Are Your Data in the Double Star Catalogs?

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!

                                          OBITUARIES

     
                                   PAUL COUTEAU (1923-2014)

C'est a l'age de 10 ans que le jeune COUTEAU commence a s'intresser a l'Astronomie. 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.

                           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.

                            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.
