Abstract:
    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 2.5M{Jup} and orbital separations of 0.76 and
    1.58AU, 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.
