Abstract (from CDS):

We present VLT eclipse photometry for the giant planet CoRoT-1b. We observed a transit in the R-band filter and an occultation in a narrow filter centered on 2.09µm. Our analysis of this new photometry and published radial velocities, in combination with stellar-evolutionary modeling, leads to a planetary mass and radius of 1.07^+0.13_–0.18M_Jup and 1.45^+0.07_–0.13R_Jup, confirming the very low density previously deduced from CoRoT photometry. The large occultation depth that we measure at 2.09µm (0.278^+0.043_–0.066%) is consistent with thermal emission and is better reproduced by an atmospheric model with no redistribution of the absorbed stellar flux to the night side of the planet.
