Antarctic is an ideal and unique site on Earth for astronomical observations. Due to its low water content, low turbulent atmosphere zone and 24 hours uninterrupted observations during its winter time, it is an extremely good place for transit exoplanet survey which requires high photometric precision. 4 small telescopes (CSTAR) with diameter 14.5 centimeters have been put in Antarctic Kunlun station (Dome A), and operated since 2008. Three telescopes (AST3) with diameters around 50 centimeters each will be placed in Dome A within next few years. Here we report our planned transit survey in AST3, aiming at finding exoplanets at middle distance to their host stars. The planet candidates found through AST3 will be followed by a late-coming 2.5-meter telescope called KDUST. Some preliminary exoplanet candidates revealed by the ongoing CSTAR will be presented. The work is supported by Nanjing University’s 985 Funds, and Funds form NSFC.
