STELLAR FLARES IN THE CSTAR FIELD: RESULTS FROM THE 2008 DATA SET Academic Article uri icon

abstract

  • ABSTRACT The Chinese Small Telescope ARray (CSTAR) is the first Chinese astronomical instrument placed in Antarctica. It is a group of four identical, fully automatic telescopes, with afield of view (FOV) of 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, CSTARtookhigh-precision photometric data of 18,145 stars around the South Celestial Pole. At and 12, the photometric precision reaches 8 mmag and 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 thedetected flares along with their stellar properties are presented in this work.
