Accurate radius and mass of the transiting exoplanet OGLE-TR-132b.

Abstract (from CDS):

The exoplanet OGLE-TR-132b belongs to the new class of very hot giant planets, together with OGLE-TR-56b and OGLE-TR-113b, detected by their transits. Recently, radial velocity measurements provided a planetary mass estimate for OGLE-TR-132b. The planet parameters, however, were poorly constrained, because of the very shallow transit in the OGLE light curve. In this letter, based on new VLT/FORS2 photometric follow-up of OGLE-TR-132 of unprecedented quality (1.2mmag relative photometry), we confirm the planetary nature of the orbiting object, and we derive an accurate measurement of its radius and mass: 1.13±0.08RJ and 1.19±0.13MJ. The refined ephemeris of OGLE-TR-132 transits is T0=2453142.5888 and P=1.689857days.
