Abstract

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 m2 sin i = 2.5 MJup and is orbiting the metal-rich star HD 43691 with period P = 40 days and eccentricity e = 0.14. The other planet has a minimum mass m2 sin i = 5.6 MJup and orbits the slightly metal-rich star HD 132406 with period P = 974 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.
