The SOPHIE search for northern extrasolar planets: XIII. Two planets around M-dwarfs Gl617A and Gl96
We report the detection of two exoplanets and a further tentative candidate around the M-dwarf stars Gl96 and Gl617A, based on radial velocity measurements obtained with the SOPHIE spectrograph at the Observatoire de Haute-Provence. Both stars were observed in the context of the SOPHIE exoplanet con...
