Optical Follow up Photometry of the Transiting Extrasolar Planet XO-2
IAU Symposium Proceedings Series(2009)
摘要
We present; three full z-band transit, light curves for the extrasolar planet XO-2 obtained with KeplerCam and the FLWO 1.2m telescope. The system parameters were determined fitting the data to transit models using a Maxkov Chain Monte Carlo simulation (MCMC). The main results presented in this poster are revised values for the parameters R-p/R-s, a/R-s and b.
