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 Rsolar. 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.
