Abstract (from CDS):

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 m2sini=2.5MJup and is orbiting the metal-rich star HD43691 with period P=40days and eccentricity e=0.14. The other planet has a minimum mass m2sini=5.6MJup and orbits the slightly metal-rich star HD132406 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.
