Abstract.
We are carrying out a Doppler search for short-period giant planets around 100 solar-type stars in nearby open clusters aged 30-150 Myr. Finding planets around such young stars will provide unique constraints on the formation and early dynamical evolution of planetary systems. As the properties of our targets are precisely known, we can subtract the large-amplitude radial velocity signal induced by rotating spots to recover the lower-amplitude Doppler signal produced by a close-in giant planet. We present here the results of a pilot study conducted with ESO/HARPS and OHP/SOPHIE. These results illustrate our methodology and demonstrate our ability to detect hot Jupiters around a subsample of representative targets.
