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…
A Planet Candidate in the Stellar Triple System HD178911
S. Zucker, D. Naef, D. W. Latham +9
We report the detection of a low-mass companion orbiting the solar-type star HD178911B, the distant component of the stellar triple system HD178911. The variability of HD178911B wa…
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…
Low-mass star formation in CG1: a diffraction limited search for pre-main sequence stars next to NX Pup
W. Brandner, J. Bouvier, E. K. Grebel +3
Using adaptive optics at the ESO 3.6m telescope, we obtained diffraction limited JHK-images of the region around the Herbig AeBe star NX Pup. We clearly resolved the close companio…
