ON THE POSSIBLE EXISTENCE OF A VERY LOW-MASS OBJECT
IN THE TRIPLE STELLAR SYSTEM GLIESE 22 (HIP 2552)
Hierarchical triple system Gl 22 consists of three red dwarfs Aa, Ab and B. The orbital
period of the inner orbit (pair Aa-Ab) is 15.64 yr, whereas that of the outer one (B
relative to the mass center of Aa-Ab) is 223.4 yr. Both orbits are coplanar.
When determining the outer orbit, a weak sinusoidal pattern in the apparent motion of the
component B has been noticed. It can be attributed to either a very unusual distribution
of observational residuals or an unseen fourth body in the system. In the latter case, the
star B would consist of the components Ba and Bb.
Under assumption of Bb to be a very low-mass object of 0.015 Msun (16 Mjupiter) on a
circular orbit around Ba with a period of ~15 yr, semimajor axis 0".35 and coplanar with
other two orbits, the observational residuals of the outer orbit are improved. In such
case, the component Ba would be moving relative to the mass center of the virtual pair
Ba-Bb on an orbit with a semimajor axis of 0".03.
These motions are illustrated in the attached Fig. 1 on which blue line corresponds to the
orbit of the Ba-Bb mass center relative to that of Aa-Ab and the red one shows the motion
of the component Ba affected by the virtual component Bb. Similar to all visual,
photographic and CCD observations, a single speckle measurement marked as "speckle (LC)"
had initially been showing the position of B relative to the light center of Aa-Ab. For
the orbits calculation, all such measurements have been reduced to the mass center of
Aa-Ab.

OMER NYS (1931-2007)
Born on 1 September 1931 at Tamise (Belgium), Omer NYS suddenly died at home in UCCLE
(Brussels) on 20 January 2007, leaving behind him a lot of regrets and sadness.
He became a member of the Royal Observatory of Belgium on 1 April 1952 in the "assistant
category" to the Scientific Staff and was directed to the Equatorial's Department under
the leadership of Dr. Sylvain AREND. He brightly passed the foreseen examinations to
"climb" its successive degrees.
His excellent basic formation permits to initiate him very early with the various
computation methods in astrometry, particularly in visual double star astronomy. Omer was
thus logically conducted to acquire good knowledge in celestial mechanics and to
participate in orbit computations. He also was involved in various shared domains as the
computation of stellar masses and dynamical parallaxes as well as of the relative radial
velocities of the components of a binary. He actively contributed in our researches
leading to the discovery of a particular spatial organization of the visual double stars
orbital planes (J. Dommanget, 2005).
His carrier has been exemplary as well by his desire to acquire some new competencies than
by his steadiness in work. Having not been aware of such qualities of our collaborator, we
would not have accepted the invitation made at a meeting at the Institut d'Astrophysique
of Paris on april 15 1980, to collaborate in recording the available astrometric,
photometric and spectroscopic data about the visual double stars needed to assure their
correct observation by the HIPPARCOS satellite of the European Space Agency (ESA). This
was a challenge, but it was with enthusiasm that we created the "Catalogue of the
components of Double and Multiple stars - CCDM" (J. DOMMANGET & O. NYS, 1994), a more
adapted version to the need of the mission, than the Index Catalogue of H. M. JEFFERS &
W. H. van den BOS, managed at the time by our USNO colleague C. E. WORLEY.
This has probably been our most extended collaboration on a common subject. Seeing that
the satellite had completed his mission and the results being published (ESA, 1997), Omer
Nys finally - almost alone - pursued the completion of the CCDM beyond his retirement and
to this sorrowed day of January 20, 2007.
Many other important activities should be mentioned, as for instance his important
collaboration in the development by S. AREND of his own researches on the "Orthogonal
Polynomia".
Omer was an upright, guarded and pleasant colleague.
All our sympathy goes to his wife and his family.
J. Dommanget

PIERRE BACCHUS (1923-2007)
An astronomer's life mainly devoted to double star astronomy
Pierre BACCHUS was born the 10th of July 1923 at M'ezi`eres (Ardennes), presently called
Charleville-M'ezi`eres in France near the Belgian border. He very soon showed a great
interest for astronomy. During his school year 1941-1942, while studying at Lyc'ee
Saint-Louis in Paris, one evening with two other students, he used a small astronomical
telescope of his own to observe the satellites of Jupiter in a gymnasium of the lyc'ee.
At the entrance examinations of both the Ecole Normale Sup'erieure and Ecole
Polytechnique, he was rated first for the written assignments and was admitted with a
prominent rank in both schools.
He easily cleared his examinations step by step and at the summer 1946, Bacchus
brilliantly passed the "agr'egation de physique". The subject of his thesis on the
"sodium" of the nocturnal and crepuscular skies had been proposed by Alfred KASTLER. After
a short stay in southern France, he went to astrometry on the advice of Andr'e DANJON and
moved to the Observatoire de Strasbourg. There, he conceived very artful ocular equipment
which, based on rotating spirals, permitted to measure simultaneously the angular
separation and the position angle of a binary star. Unfortunately, the atmospheric
turbulence blurs the images, whereas the considered equipment requires a perfect aiming on
the star.
BACCHUS concluded that his instrument was thus not usable on the Earth surface. Around
1964, with Pierre LACROUTE, he had the idea to go to space for doing astrometry with a
very high precision. The critical problem then became that of the quality of the
catalogues. Moreover, the catalogues of the northern and southern hemispheres do not join
up well because they were independently realized.
This idea gave rise to the conception of the Hipparcos satellite, essentially due to P.
LACROUTE, but the ideas of P. BACCHUS were underlying. He was actively involved in the
optical design of the satellite; his proposal to transfer of the classical corrections of
the Schmidt lens to the complex mirror remains the most original one.
Concerning the visual double stars, he studied their observability conditions by Hipparcos
and, from 1982 to 1990, he actively participated to the working group having in charge the
double star data needed for the preparation of the Hipparcos Input Catalogue. At the end
of the year 1985, he therefore started a verification project of the relative positions of
binaries that might be observed by the satellite. He identified and measured systems on
Schmidt photographic plates taken at the European Southern Observatory (ESO) and of which
a copy was available at the Royal Observatory (Belgium) where he weekly went to
collaborate with the team J. Dommanget/O. Nys. These data were needed for the Catalogue of
the Components of Double and Multiple stars (CCDM) of J. Dommanget, coordinator of the
double star working group, and his collaborator O. Nys.
In 1961, Bacchus left Strasbourg for Lille where he was successor to Vladimir Kourganoff
as professor of astronomy at the University and head of the laboratory of astronomy until
his retirement in 1986.
A computer expert impassionate for the computer languages, in particular the Algol
language, he was also creator and director of the "Laboratoire de calcul et d'informatique
fondamentale de l'Universit'e de Lille".
In 1973, the Conseil International de la Langue Fran,caise launched the project of a
"Vocabulaire d'Astronomie". A working group of European astronomers was created and Pierre
BACCHUS was chosen for conducting its work. He supervised and realized the manuscript.
Therefore he devised and implemented software which enabled to justify the text on the
right side.
Pierre Bacchus was very much involved in the history of astronomy and was a member of the
"Commission des cadrans solaires" of SAF (Soci'et'e Astronomique de France) some years
after its foundation, Pierre Bacchus was one of the king-bolts of a team who published a
voluminous work on the mottos of sundials.
At the meeting of the Commission des Etoiles Doubles of the SAF at Lille in august 1984,
Fr'ed'eric Honnart invited Pierre Bacchus to become a member of this commission as a
scientific councilor.
He proposed to its members to contribute to his verification project of 1985 of relative
positions of the components of double stars and in 1986 and 1987, advised Pierre Durand in
preparing various missions for this purpose at the observatories of Haute-Provence, Nice
and Pic du Midi. Pierre Bacchus helped to the development of the double image micrometer
conceived by Bernard Lyot, by investigating the birefringence of the spar plate, which is
its fundamental optical component.
He actively participated to the meetings of the Commission which profited by his
experience as a physicist, an astronomer and a mathematician. In particular, for modeling
the spreading of the stellar images in the illumination map of the field of a visual
double star, he suggested, to replace an empirical formula due to Otto Franz by a more
representative and simpler one.
Till just before his death on May 28th, Pierre Bacchus actively participated to the
working group on "radial velocities", raised up by Jean Dommanget a few years ago, with
the aim to investigate the space orientation of the orbital planes of the orbital
binaries, by the removal of the ambiguity on the direction of their ascending nodes. In
the winter 2006-2007, he developed software in C-language of the type "data base steering"
for collecting the useful observations to the program "radial velocities".
When he participated to seminaries or meetings, his comments were always given with ease,
acumen, an acute sense of the progression in his statements, generally without notes. His
friend's amateur astronomers and his students unanimously recognize his great teaching
qualities.
The Commission des Etoiles Doubles has lost a kind and particularly shrewd counsellor, who
brought very much during more than two decennaries, more particularly by the relevance of
his remarks and commentaries on numerous talks given during the meetings.
One shall keep for a long time the memory of Pierre Bacchus, a man good and generous,
endowed by a prodigious capacity of assimilation and of inventing, charming in his
singularity.
