M Dwarfs Found In The First Byurakan Spectral Sky Survey Data Base. Gaia EDR3 And TESS Data. Some Preliminary Results
Abstract
In order to gain more information on the 236 M dwarfs identified in the First Byurakan Survey (FBS) low-resolution (lr) spectroscopic database, Gaia EDR3 high-accuracy astrometric and photometric data and Transiting Exoplanet Survey Satellite (TESS) data are used to characterize these M dwarfs and their possible multiplicity.
