Abstract
We present radial velocity measurements obtained for the search for extrasolar planets with the spectrograph SOPHIE at the 1.93m telescope at Haute-Provence Observatory. Targets were selected from catalogs observed with ELODIE, mounted previously at the telescope, in order to detect long-period planets with an extended database close to 15 years.
We present two new Jupiter-analogue candidates, as well as the first reliable orbit for HD24040b and refined orbits for HD154345b, HD89307b (Boisse et al. 2012).
We discuss the main properties of this new population of long-period Jupiter-mass planets. These stars are preferential targets for direct-imaging or astrometry follow-up to constrain the system parameters and for higher precision radial velocity to search for lower mass planets, aiming to find a Solar System twin.
