Abstract (from CDS):

The CoRoT exoplanet science team announces the discovery of CoRoT-11b, a fairly massive hot-Jupiter transiting a V=12.9mag F6 dwarf star (M_*=1.27±0.05M_☉, R_*=1.37±0.03R_☉, T_eff=6440±120K), with an orbital period of P=2.994329±0.000011-days and semi-major axis a=0.0436±0.005AU. The detection of part of the radial velocity anomaly caused by the Rossiter-McLaughlin effect shows that the transit-like events detected by CoRoT are caused by a planet-sized transiting object in a prograde orbit. The relatively high projected rotational velocity of the star (vsini_*=40±5km/s) places CoRoT-11 among the most rapidly rotating planet host stars discovered so far. With a planetary mass of M_p=2.33±0.34M_Jup and radius R_p=1.43±0.03R_Jup, the resulting mean density of CoRoT-11b (ρ_p=0.99±0.15g/cm³) can be explained with a model for an inflated hydrogen-planet with a solar composition and a high level of energy dissipation in its interior.
