VizieR Online Data Catalog: Photometry of Proxima Centauri observed by BSST (Liu+, 2018)
Abstract
We started the photometric monitoring of Proxima Centauri in Antarctica right after the announcement of the discovery of Proxima Centauri b (Anglada-Escude et al. 2016Natur.536..437A). In August and September, Proxima Centauri is not observable at almost all observatories around the world, except for the sites in Antarctica. Our observations were carried out using the Bright Star Survey Telescope (BSST; Tian et al. 2016, Sci. Bull. 61 383) deployed at the Chinese Antarctic Zhongshan station (south 69°22'23", east 76°22'17"). BSST (Tian et al. 2016, Sci. Bull. 61 383) is optimally designed for searching planetary transits of bright stars and will join the ongoing survey at Kunlun station. It has an aperture size of 300 mm and is equipped with a large frame 4 Kx4 K CCD camera to receive starlight from a 3.4°x3.4° field of view (Li et al. 2015, ChOpL 13 11). We monitored the photometry of Proxima Centauri over 10 nights between 2016 August 29 and September 21. The star was observed in its white light, without any filter. The typical airmass toward Proxima Centauri was 1.4 all throughout the observation campaign. Five exposures of 3 s are combined as a photometric point, and a typical cadence of data points is 220 s.
