Abstract

We present the detection of a 0.47 $M_{{\rm Jup}}$ planet in a 44-day period eccentric trajectory (e = 0.39) orbiting the metal-rich star HD 45652. This planet, the seventh giant planet discovered in the context of the ELODIE metallicity-biased planet search program, is also confirmed using higher precision radial-velocities obtained with the CORALIE and SOPHIE spectrographs. The orbital period of HD 45652b places it in the middle of the “gap” in the period distribution of extra-solar planets.

Based on observations collected at the La Silla-Paranal Observatory, ESO (Chile) with the CORALIE spectrograph at the Euler 1.2-m Swiss Telescope, and with the ELODIE and SOPHIE spectrographs at the 1.93-m telescope of the Observatoire de Haute Provence (OHP), France.
