We report here the discovery of two planet candidates as a result of our planet-search programme biased in favour of high-metallicity stars, using the ELODIE spectrograph at the Observatoire de Haute Provence. One candidate has a minimum mass MJup and is orbiting the metal-rich star HD 43691 with period days and eccentricity . The other planet has a minimum mass MJup and orbits the slightly metal-rich star HD 132406 with period days and eccentricity e = 0.34. Additional observations for both stars were performed using the new SOPHIE spectrograph that replaces the ELODIE instrument, allowing an improved orbital solution for the systems.
Key words: stars: individual: HD 43691 / stars: individual: HD 132406 / planetary systems / techniques: radial velocities
