Scientific paper

Star hosting planets have been shown to be more metal rich than single stars of the solar neighborhood. We present here a metallicity-biased planet-search program on-going since 18 months at Haute-Provence Observatory with the ELODIE spectrograph, where the target sample are high metallicity stars. We use a cross-correlation technique for radial-velocity estimates, together with a photometric transit search performed with the 120-cm telescope at the Haute-Provence Observatory. This program has already conducted to the discovery of two new planets candidates orbiting HD 118203 and HD 189733, and to the confirmation of another one orbiting HD 149143.
