Abstract
The Antarctic plateau is one of the best observing sites on the surface of the Earth thanks to its extremely cold, dry, stable and transparent atmosphere conditions. Various astronomical activities are underway there and the Chinese Center for Antarctic Astronomy (CCAA) is dedicated to developing Antarctic astronomy at the highest point, Dome A or the Chinese Kunlun station. So far a large number of images have been collected from a 14.5-cm quad-telescope called the Chinese Small Telescope ARray (CSTAR) and the first two of a trio of 50-cm Antarctic Survey Telescopes (AST3-1 and AST3-2).
Highlights
6 months of the 2008, 2009, 2010 Antarctic winters, respectively ([5,6,7,8,9])
Those long-term highcadence data showed that the high-precision long-term photometry is possible at Dome A, Antarctica thanks to its long, continuous, stable and clear atmosphere conditions
Based on time-series photometry of 92583 stars measured by AST3-1, 560 variable stars were detected with i magnitude ≤ 16.5 mag during 8 days of observations ([10])
Summary
6 months of the 2008, 2009, 2010 Antarctic winters, respectively ([5,6,7,8,9]). Those long-term highcadence data showed that the high-precision long-term photometry is possible at Dome A, Antarctica thanks to its long, continuous, stable and clear atmosphere conditions. A large number of time-series photometric data in Table 1 had been acquired since 2008 from the first-generation optical telescope CSTAR ([1]) and the second-generation optical telescopes AST3-1, AST3-2 ([2,3,4]).
