Abstract (from CDS):

In the framework of the search for extrasolar planets and brown dwarfs around early-type stars, we present the results obtained for the F-type main-sequence star HD 60532 (F6V) with HARPS. Using 147 spectra obtained with HARPS at La Silla on a time baseline of two years, we studied the radial velocities of this star. HD 60532 radial velocities are periodically variable, and the variations have a Keplerian origin. This star is surrounded by a planetary system of two planets with minimum masses of 1 and 2.5MJup and orbital separations of 0.76 and 1.58 AU, respectively. We also detect high-frequency, small-amplitude (10m/s peak-to-peak) pulsations. Dynamical studies of the system point toward a possible 3:1 mean-motion resonance that should be confirmed within the next decade.
