Exoplanets in the Antarctic Sky. I. The First Data Release of AST3-II (CHESPA) and New Found Variables within the Southern CVZ of TESS
Hui Zhang, Zhouyi Yu, Ensi Liang +37
Located at Dome A, the highest point of the Antarctic plateau, the Chinese Kunlun station is considered to be one of the best ground-based photometric sites because of its extremel…
Meteorological data from KLAWS-2G for an astronomical site survey of Dome A, Antarctica
Yi Hu, Keliang Hu, Zhaohui Shang +8
We present an analysis of meteorological data from the second generation of the Kunlun Automated Weather Station (KLAWS-2G) at Dome A, Antarctica during 2015 and 2016. We find that…
The First Release of the AST3-1 Point Source Catalogue from Dome A, Antarctica
Bin Ma, Zhaohui Shang, Yi Hu +35
The three Antarctic Survey Telescopes (AST3) aim to carry out time domain imaging survey at Dome A, Antarctica. The first of the three telescopes (AST3-1) was successfully deployed…
Variable Stars Observed in the Galactic Disk by AST3-1 from Dome A, Antarctica
Lingzhi Wang, Bin Ma, Gang Li +15
AST3-1 is the second-generation wide-field optical photometric telescope dedicated to time domain astronomy at Dome A, Antarctica. Here we present the results of band images su…
Meteorological data for the astronomical site at Dome A, Antarctica
Yi Hu, Zhaohui Shang, Michael C. B. Ashley +7
We present an analysis of the meteorological data collected at Dome A, Antarctica by the Kunlun Automated Weather Station, including temperatures and wind speeds at eight elevation…
Problems with twilight/supersky flat-field for wide-field robotic telescopes and the solution
Peng Wei, Zhaohui Shang, Bin Ma +3
Twilight/night sky images are often used for flat-fielding CCD images, but the brightness gradient in twilight/night sky causes problems of accurate flat-field correction in astron…
The nonlinear photon transfer curve of CCDs and its effects on photometry
Bin Ma, Zhaohui Shang, Lifan Wang +3
The photon transfer curve (PTC, variance vs. signal level) is a commonly used and effective tool in characterizing CCD performance. It is theoretically linear in the range where ph…
A new method of CCD dark current correction via extracting the dark information from scientific images
Bin Ma, Zhaohui Shang, Yi Hu +3
We have developed a new method to correct dark current at relatively high temperatures for Charge-Coupled Device (CCD) images when dark frames cannot be obtained on the telescope.…
Data characterization using artificial-star tests: performance evaluation
Yi Hu, Licai Deng, Richard de Grijs +1
Traditional artificial-star tests are widely applied to photometry in crowded stellar fields. However, to obtain reliable binary fractions (and their uncertainties) of remote, dens…
