VizieR Online Data Catalog: Extremely Low Mass Ratio Contact Binaries I. 10 systems (Li+, 2022)
Abstract
4m-class telescopes were applied to observe the ten Extremely low mass ratio contact binaries (ELMRCBs). The information of the four meter-class telescopes is as follows. The 60cm Ningbo Bureau of Education and Xinjiang Observatory Telescope (NEXT). This telescope is equipped with an FLI PL23042 CCD, resulting a field of view of 22x22' The Tsinghua-NAOC 80cm Telescope (TNT). The PIXIS 1300B CCD was used for this telescope, providing a field of view of 11.4x11.1". The 85cm telescope at the Xinglong Station of National Astronomical Observatories (XL85). This telescope used an Andor DZ936 CCD, and its field of view is 32x32'. The Weihai Observatory 1.0m telescope of Shandong University (WHOT. The PIXIS 2048B CCD was equipped on this telescope, and the field of view is 12x12'.
All the ten systems have been observed as part of the The Large sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) low-resolution spectroscopic survey. LAMOST is a 4m reflecting Schmidt telescope with a 5deg field of view. It has 4000 fibers mounted on its focal plane to make a very high spectral acquisition rate. The spectral resolution of the low-resolution spectroscopic survey is R~1800 covering the wavelength range of about 3700-9000Å. (2 data files).- Publication:
