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 $m_2\sin{i} = 2.5$MJupand is orbiting the metal-rich star HD 43691with period $P = 40$days and eccentricity $e=0.14$. The other planet has a minimum mass $m_2\sin{i} = 5.6$MJupand orbits the slightly metal-rich star HD 132406with 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.
