Observed brightness variation of OGLE-TR-3

This chart shows the brightness variation ("light-curve") of the star OGLE-TR-3 obtained during the OGLE observations. The crosses correspond to the observations and the fully drawn curve represents a model fit, with the stellar parameters from the analysis of the UVES spectra (1 solar radius and 1 solar mass) and the planetary parameters from the velocity analysis (0.6 Jupiter mass). The best fit allows determination of the planet''s size as about 200,000 km (1.4 times the size of Jupiter).
