Abstract (from CDS):

We report the detection of a rare transiting brown dwarf with a mass of 59M_Jup and radius of 1.1R_Jup around the metal-rich, [Fe/H]=+0.44, G9V star CoRoT-33. The orbit is eccentric (e=0.07) with a period of 5.82d. The companion, CoRoT-33b, is thus a new member in the so-called brown dwarf desert. The orbital period is within 3% to a 3:2 resonance with the rotational period of the star. CoRoT-33b may be an important test case for tidal evolution studies. The true frequency of brown dwarfs close to their host stars (P<10d) is estimated to be approximately 0.2% which is about six times smaller than the frequency of hot Jupiters in the same period range. We suspect that the frequency of brown dwarfs declines faster with decreasing period than that of giant planets.
