Outline Background Observation Data reduction Light curve analysis Future plan
Background It is known well that the transit of exoplanet can provide information about its radii and orbital inclination which can be used to derive its mass and density, furthermore, to infer the clue on its formation and evolution. The monitoring for changes on orbital inclination, transit time and duration makes it possible to detect other low-mass exoplanets. Here, we give out the preliminary results of our follow-up observation on transit events and future plan on this topic in China.
Observation Instruments 1.0m telescope+2Kx2K CCD at Yunnan Observatory R filter
85cm telescope+1Kx1K CCD at Xinglong station of NAOC. R filter
Research projects Defocus observation for transit events Improve the accuracy of transit light curves Open cluster transit survey Discover new transit exoplanet candidates LiJET follow-up confirmation for the brighter ones of them
