@misc{Gigoyan_K._K._The, author={Gigoyan, K. K. and Gigoyan, K. S. and Kostandyan, G. R.}, howpublished={online}, abstract={A new value-added catalogue of late-type stars (LTSs), including M dwarfs, M giants, as well as new C (carbon) stars of N and CH types, was published from the analysis of the Digitized First Byurakan Survey (DFBS) spectral database. 1091 LTSs have been confirmed (243 M giants, 834 M dwarfs, and 14 C stars). All these objects were selected as LTS candidates when analysing the DFBS plates. For spectral type confirmation, the Gaia DR3 low-resolution BP/RP spectroscopic database has been used. To clarify the nature of the newly confirmed objects, Gaia DR3 photometric data and transiting Exoplanet Survey satellite (TESS) Input Catalog (TIC) data (masses, radii, effective temperatures, colors, distances, etc.) have been used. Using distances derived from the parallax in Gaia DR3, BP-RP color versus G-band absolute magnitude diagram (color-absolute magnitude diagram-CaMD) were constructed. Part of the newly confirmed M dwarfs presents binary systems.}, title={The Third Catalogue of the First Byurakan Survey of Late-Type Stars}, type={Electronic journal}, keywords={Astrometry, Space Sciences, Archaeoastronomy and Astronomy in Culture}, }
