Abstract:
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 14.3M{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 quite
circular orbit supports a formation in a gaseous protoplanetary disk.
Description:
We acquired 20 spectra of HD16760 within objAB mode with SOPHIE
between December 2006 and October 2008.
