Abstract
We present the detection of a 0.47 MJup planet in a 44-day period eccentric trajectory (e = 0.39) orbiting the metal-rich star HD45652.
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 HD45652b places it in the middle of the “gap” in the period distribution of extra-solar planets.
