Abundance ratios of volatile vs. refractory elements in planet-harbouring stars: hints of pollution?
A. Ecuvillon, G. Israelian, N. C. Santos +2
We present the [X/H] trends as function of the elemental condensation temperature Tc in 88 planet host stars and in a volume-limited comparison sample of 33 dwarfs without detected…
A Massive Planet to the Young Disc Star HD 81040
A. Sozzetti, S. Udry, S. Zucker +9
We report the discovery of a massive planetary companion orbiting the young disc star HD 81040. Based on five years of precise radial-velocity measurements with the HIRES and ELODI…
The CORALIE survey for southern extrasolar planets XIV. HD 142022 b: a long-period planetary companion in a wide binary
A. Eggenberger, M. Mayor, D. Naef +5
We report precise Doppler measurements of HD 142022 obtained during the past six years with the CORALIE echelle spectrograph at La Silla Observatory together with a few additional…
Extrasolar planets and brown dwarfs around A-F type stars III. Beta-Pictoris : looking for planets, finding pulsations
F. Galland, A. M. Lagrange, S. Udry +4
In the frame of the search for extrasolar planets and brown dwarfs around early-type stars, we present the results obtained on Beta-Pictoris, which is surrounded by a circumstellar…
Extrasolar planets and brown dwarfs around A-F type stars. II. A planet found with ELODIE around the F6V star HD 33564
F. Galland, A. M. Lagrange, S. Udry +4
We present here the detection of a planet orbiting around the F6V star HD 33564. The radial velocity measurements, obtained with the ELODIE echelle spectrograph at the Haute-Proven…
Oscillations on the star Procyon
Francois Bouchy, Andre Maeder, Michel Mayor +3
Stars are sphere of hot gas whose interiors transmit acoustic waves very efficiently. Geologists learn about the interior structure of Earth by monitoring how seismic waves propaga…
