摘要：

We report the discovery by the CoRoT satellite of a new transiting giant planet in a 2.83 days orbit about a V = 15.5 solar analog star (M-* = 1.08 +/- 0.08 M-circle dot, R-* = 1.1 +/- 0.1 R-circle dot, T-eff = 5675 +/- 80 K). This new planet, CoRoT-12b, has a mass of 0.92 +/- 0.07 M-Jup and a radius of 1.44 +/- 0.13 R-Jup. Its low density can be explained by standard models for irradiated planets.
