Data Release of the AST3-2 Automatic Survey from Dome A, Antarctica
Xu Yang, Yi Hu, Zhaohui Shang +18
AST3-2 is the second of the three Antarctic Survey Telescopes, aimed at wide-field time-domain optical astronomy. It is located at Dome A, Antarctica, which is by many measures the…
A wide star-black-hole binary system from radial-velocity measurements
Jifeng Liu, Haotong Zhang, Andrew W. Howard +52
All stellar mass black holes have hitherto been identified by X-rays emitted by gas that is accreting onto the black hole from a companion star. These systems are all binaries with…
Stellar Variability and Flare Rates from Dome A, Antarctica using 2009 and 2010 CSTAR Observations
Ryan J. Oelkers, Lucas M. Macri, Lifan Wang +12
The Chinese Small Telescope ARray (CSTAR) carried out high-cadence time-series observations of 20.1 square degrees centered on the South Celestial Pole during the 2008, 2009 & 2010…
Difference Image Analysis of Defocused Observations with CSTAR
Ryan J. Oelkers, Lucas M. Macri, Lifan Wang +13
The Chinese Small Telescope ARray (CSTAR) carried out high-cadence time-series observations of 27 square degrees centered on the South Celestial Pole during the Antarctic winter se…
Photometry of Variable Stars from Dome A, Antarctica: Results from the 2010 Observing Season
Lingzhi Wang, Lucas M. Macri, Lifan Wang +17
We present results from a season of observations with the Chinese Small Telescope ARray (CSTAR), obtained over 183 days of the 2010 Antarctic winter. We carried out high-cadence ti…
Photometry of Variable Stars from Dome A, Antarctica
Lingzhi Wang, Lucas M. Macri, Kevin Krisciunas +18
Dome A on the Antarctic plateau is likely one of the best observing sites on Earth thanks to the excellent atmospheric conditions present at the site during the long polar winter n…
