Abstract

The transiting exoplanetary system WASP-11/HAT-P-10 was observed using the CCD camera at Yunnan Observatories, China from 2008 to 2011, and four new transit light curves were obtained. Combined with published radial velocity measurements, the new transit light curves are analyzed along with available photometric data from the literature using the Markov Chain Monte Carlo technique, and the refined physical parameters of the system are derived, which are compatible with the results of two discovery groups, respectively. The planet mass is M-p = 0.526 +/- 0.019 M-J, which is the same as West et al.'s value, and more accurately, the planet radius R-p = 0.999(-0.018) (+0.029) R-J is identical to the value of Bakos et al. The new result confirms that the planet orbit is circular. By collecting 19 available mid-transit epochs with higher precision, we make an orbital period analysis for WASP11b/HAT-P-10b, and derive a new value for its orbital period, P = 3.72247669 days. Through an (0 C) study based on these mid-transit epochs, no obvious transit timing variation signal can be found for this system during 2008-2012.
