Photometry of Variables from Dome A, Antarctica
Abstract Dome A on the Antarctic plateau is likely one of the best observing sites on Earth (Saunders et al . 2009). We used the CSTAR telescope (Yuan et al . 2008) to obtain time-series photometry of 10 4 stars with i >14.5 mag during 128 days of the 2008 Antarctic winter season (Wang et al...
