Abstract:
Fewer giants planets are found around M dwarfs than around more
massive stars, and this dependence of planetary characteristics on the
mass of the central star is an important observational diagnostic of
planetary formation theories. In part to improve on those statistics,
we are monitoring the radial velocities of nearby M dwarfs with the
HARPS spectrograph on the ESO 3.6m telescope. We present here the
detection of giant planets around two nearby M0 dwarfs: planets, with
minimum masses of respectively 5 Jupiter masses and 1 Saturn mass,
orbit around Gl 676A and HIP 12961.
