The Chinese Small Telescope ARray (CSTAR) is a group of four identical, fullyautomated, static 14.5 cm telescopes. CSTAR is located at Dome A, Antarcticaand covers 20 square degree of sky around the South Celestial Pole. Theinstallation is designed to provide high-cadence photometry for the purpose ofmonitoring the quality of the astronomical observing conditions at Dome A anddetecting transiting exoplanets. CSTAR has been operational since 2008, and hastaken a rich and high-precision photometric data set of 10,690 stars. In thefirst observing season, we obtained 291,911 qualified science frames with20-second integrations in the i-band. Photometric precision reaches about 4mmag at 20-second cadence at i=7.5, and is about 20 mmag at i=12. Using robustdetection methods, ten promising exoplanet candidates were found. Four of thesewere found to be giants using spectroscopic follow-up. All of these transitcandidates are presented here along with the discussion of their detailedproperties as well as the follow-up observations.
