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 ( 1.2 millimagnitude relative photometry ) , we confirm the planetary nature of the orbiting object , and we derive an accurate measurement of its radius and mass : 1.13 \pm 0.08 R _ { J } and 1.19 \pm 0.13 M _ { J } .
The refined ephemeris of OGLE-TR-132 transits is T _ { 0 } = 2453142.5888 and P = 1.689857 days .
