The ELODIE Planet Search: Synthetic View of the Survey and its Global Detection Threshold
D. Naef, M. Mayor, J. L. Beuzit +4
In this paper, we give a synthetic view of the ELODIE Planet Search Survey: a short description of our instrument and the surveyed sample as well as a brief review of our detection…
Accurate masses of very low mass stars: IV Improved mass-luminosity relations
X. Delfosse, T. Forveille, D. Ségransan +4
We present improved visual and near-infrared empirical mass-luminosity relations for very low mass stars (M0.6~\Msol). These relations make use of all stellar masses in this ran…
Accurate masses of very low mass stars: III 16 new or improved masses
D. Ségransan, X. Delfosse, T. Forveille +4
We have obtained adaptive optics images and accurate radial velocities for 7 very low mass systems, in the course of a long term effort to determine accurate masses for very low ma…
New neighbours. I. 13 new companions to nearby M dwarfs
X. Delfosse, T. Forveille, J. -L. Beuzit +3
We present preliminary results of a radial-velocity search for companions to a volume limited sample of M dwarfs. Typical accuracy range between 10m/s for the brighter stars and 70…
The closest extrasolar planet: A giant planet around the M4 dwarf Gl 876
Xavier Delfosse, Thierry Forveille, Michel Mayor +3
High precision radial velocity observations of the nearby M4 dwarf Gl 876 with the Observatoire de Haute Provence 1.93 m telescope and the new 1.20 m swiss telescope at la Silla in…
