中国小型望远镜阵列(CSTAR)是在南极洲Dome A建造的第一个望远镜设施。在2008年的观测季节,该装置提供了长基线和高节奏的测光观测,在i波段的18,145目标在20度2?>南天极周围的CSTAR场,目的是监测Dome A的天文观测质量并探测各种类型的光度变化。使用灵敏且强大的检测方法,我们从该数据集中发现了274个潜在变量,其中83个是新发现的。我们的特点,其中大部分,提供的周期,幅度和类的变化。所有这些变量的目录都沿着讨论了它们的统计特性。
The Chinese Small Telescope Array (CSTAR) is the first telescope facility built at Dome A, Antarctica. During the 2008 observing season, the installation provided long-baseline and high-cadence photometric observations in the i-band for 18,145 targets within 20 deg 2 ?> CSTAR field around the South Celestial Pole for the purpose of monitoring the astronomical observing quality of Dome A and detecting various types of photometric variability. Using sensitive and robust detection methods, we discover 274 potential variables from this data set, 83 of which are new discoveries. We characterize most of them, providing the periods, amplitudes, and classes of variability. The catalog of all these variables is presented along with the discussion of their statistical properties.
