Abstract (from CDS):

We report the discovery by the CoRoT space mission of a transiting brown dwarf orbiting a F7V star with an orbital period of 3.06-days. CoRoT-15b has a radius of 1.12+0.30–0.15RJup and a mass of 63.3±4.1MJup, and is thus the second transiting companion lying in the theoretical mass domain of brown dwarfs. CoRoT-15b is either very young or inflated compared to standard evolution models, a situation similar to that of M-dwarf stars orbiting close to solar-type stars. Spectroscopic constraints and an analysis of the lightcurve imply a spin period in the range 2.9-3.1-days for the central star, which is compatible with a double-synchronisation of the system.
