Abstract:
We present a new value-added catalogue of late-type stars (LTS), M
giants, M dwarfs as well as new C (carbon) stars of N and CH-types
from the analysis of the Digitized First Byurakan Survey (DFBS)
spectral data base. A total of 243 M giants, 834 M dwarfs and 14 C
stars, namely 1091 objects have been confirmed. When analysing the
DFBS plates, we selected all these objects as LTS candidates. For
spectral type confirmation, we have used the Gaia DR3 low-resolution
BP/RP spectroscopic data base. To clarify the nature of newly
confirmed objects, Gaia DR3 photometric data and Transiting Exoplanet
Survey Satellite (TESS) Input Catalog (TIC) data (masses, radii,
effective temperatures, colours, distances, etc.) have been used.
Using distances derived from the parallaxes in Gaia DR3, we
constructed BP-RP colour versus G-band absolute magnitude diagram
(colour-absolute magnitude diagram-CaMD). These confirmations of a
large number of completely new objects represent a very significant
extension in the census of M giants, faint N-type asymptotic giant
branch C stars, CH-type giants at high Galactic latitudes. Some
objects are located more than 8 kpc from the Galactic plane. Part of
the newly confirmed DFBS M dwarfs present binary systems, mainly pairs
of M dwarfs such as M dwarf plus M dwarf, and also M dwarf plus White
Dwarf (WD). Most probably, some of the newly confirmed early-type
CH-giants at high Galactic latitudes also present binary systems. The
ZTF and TESS phased light curves are presented for more interesting
objects among the samples of the DFBS LTS confirmed.
Description:
A new catalogue of late-type stars and C stars has been created from
the DFBS spectral data base, including new M giants, M dwarfs, and C
stars, with spectral type confirmation using Gaia DR3 spectroscopic
data and photometric measurements.
