ANNOUNCEMENT
A MODEL OF THE ORIENTATION OF THE ORBITAL PLANES OF THE VISUAL DOUBLE STARS
A research made at the Observatoire Royal de Belgique some thirty-five years ago by J.
Dommanget and O. Nys, has shown some specific space organisation of the orbital planes
of the visual double stars on the contrary of what was thought since more than a century.
A tri-dimensional model based on 70 stars showed this organisation very clearly especialy
in the Sun's environment. Twenty years later a second research (1982-1987) concerning 145
stars, confirmed this result which was observed with more precision on a second model
that was exhibited, during the IAU Colloquium n.97 "Wide components in double and
multiple stars" held at Brussels in 1987. (See: Astrophysics and Space Science, 142, 1988,
pp. 171-176).
A short presentation of this model has recently been given in the Bulletin de la
Commission des Etoiles doubles de la Societe Astronomique de France, n.42 of
march 2004, pp. 13-14 and an historical synthesis of the various researches made on this
subject since 1838 by J. H. MADLER will appear in Ciel et Terre n.121, 1, 2005.
On these occasions and on that of a few talks on the subject, it was decided to transfer
this model from the Observatoire Royal de Belgique to the Observatoire de la Cote d'Azur,
France where it will be preserved. In the framework of the project "Museal", near to the
historical refractors of the Nice Observatory, this model will be integrated in the
presentation devoted to the double star researches.

GEOFFREY G. DOUGLASS (1942 - 2005)
We have the sad duty to report the passing of longtime Commission 26 member
Geoffrey G. Douglass, who died 15 February 2005 after a long illness.
Geoff worked at the U.S. Naval Observatory for over 30 years, until his retirement
in January 1999. Much of his work involved observations of visual double stars,
from collaborating on the photographic program in the late 1960's to development
of the USNO's speckle interferometry program throughout the 1990's. A brief summary
of his work can be found at http://ad.usno.navy.mil/wds/history/douglass.html .
Geoff collaborated with Charles Worley from 1968 until Charles' death in December
1997, writing much of the double star software and assisting in the production of
the observatory's double star catalogs. It was often joked that the "W" and "D" in
the WDS (officially the "Washington Double Star" catalog) really stood for
"Worley" and "Douglass".
During his last year at the observatory he oversaw the publication of over 10,000
speckle observations, and guided the recently hired Brian Mason (Charles' replacement)
in the management of the double star program. He continued to have an interest in the
activities at the USNO even during his long hospitalizaton, and was regularly sought
out for his knowledge on instrumentation and earlier observations.
Those of you who knew Geoff also knew he battled illness for many years. He
was a symbol of the worthiness of organ donation, living for some two decades
following a kidney transplant, before succumbing to complications following kidney
failure.
Geoff is survived by his wife Doris, with whom he shared a love of cats and
classical music, as well as passionate religous beliefs. He will be sorely missed by
his many friends and colleagues.
