We report on the discovery of a substellar companion or a massive Jupiter orbiting the G5V
star HD 16760 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 14.3${M} _ {\rm Jup} $, an orbital
period of 465 days and an eccentricity of 0.067, HD 16760b seems to be located just at the
end of the mass distribution of giant planets, close to the planet/brown-dwarf transition. Its …

We report on the discovery of a substellar companion or a massive Jupiter orbiting the G5V star HD 16760 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 14.3 , an orbital period of 465 days and an eccentricity of 0.067, HD 16760b 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.
