The Transit Light Curve Project. IV. Five Transits of the Exoplanet OGLE-TR-10b
Abstract
We present I and B photometry of five distinct transits of the exoplanet OGLE-TR-10b. By modeling the light curves, we find the planetary radius to be RP = 1.06 +/- 0.08 RJup and the stellar radius to be RS = 1.10 +/- 0.07 Rsun. The uncertainties are dominated by statistical errors in the photometry. Our estimate of the planetary radius is smaller than previous estimates that were based on lower-precision photometry, and hence the planet is not as anomalously large as was previously thought. We provide updated determinations of all the system parameters, including the transit ephemerides.
