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