VizieR Online Data Catalog: Active giant binaries from VSX and Gaia EDR3 (Leiner+, 2022)
Abstract
To begin, we take the entire sample of RS CVn variable stars identified in the American Association of Variable Star Observers' (AAVSO) International Variable Star Index (VSX) catalog (Watson+ 2006SASS...25...47W ; see B/vsx). We use the 2021 April version of this catalog. See Section 2.1.
We match this sample of 73203 VSX RS CVns to the Gaia EDR3 catalog starting with a 1.4" searching radius. We find unique Gaia matches for 71463 sources in the VSX catalog and the cuts yield a sample of 22372 stars. See Section 2.2. Out of our original list we select a total of 1723 stars that have well-determined Gaia matches, astrometric solutions, and low-extinction values, which appear to be true RS CVns rather than misclassified MS stars. See Section 2.3. (1 data file).- Publication:
