Abstract (from CDS):

We report on the discovery of a substellar companion or a massive Jupiter orbiting the G5V star HD16760 using the spectrograph SOPHIE installed on the OHP 1.93-m telescope. Characteristics and performances of the spectrograph are presented, as well as the SOPHIE exoplanet consortium program. With a minimum mass of 14.3MJup, an orbital period of 465-days and an eccentricity of 0.067, HD16760b seems to be located just at the end of the mass distribution of giant planets, close to the planet/brown-dwarf transition. Its quite circular orbit supports a formation in a gaseous protoplanetary disk.
