英文摘要: The Chinese Small Telescope ARray (CSTAR) is the first Chinese astronomical instrument placed in Antarctica. It is a group of four identical, fully automatic 14.5 cm telescopes, with a. field of view (FOV) of 20 deg(2) centered on the South Celestial Pole. Placed at Antarctic Dome A, CSTAR is designed to provide high-cadence photometry for site monitoring and variable sources detection. During the 2008 observing season, CSTAR. took. high-precision photometric data of 18,145 stars around the South Celestial Pole. At i = 7.5 and 12, the photometric precision reaches similar to 8 mmag and similar to 30 mmag with a cadence of 20 s or 30 s, respectively. Using a robust detection method, we have found 15 stellar flares on 13 sources, including two classified variables. We have also found a linear relation between the decay times and the total durations of the stellar flares. The details of all the. detected flares along with their stellar properties are presented in this work.
