VizieR Online Data Catalog: Hot subdwarf stars with Gaia DR2 and LAMOST DR7 data (Luo+, 2021)
Abstract
By cross-matching the catalog of Geier+ (2019, J/A+A/621/A38) and LAMOST DR7, and after rejecting bad spectra, MS stars, WDs, and objects with strong CaII H&K, MgI, or CaII absorption lines, we obtained 1587 hot subdwarf stars with a spectral signal-to-noise (S/N) over 10 in the g-band.
