We present the detection of a 0.47 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.
