Verifying reddening and extinction for Gaia DR1 TGAS main sequence stars
George Gontcharov, Aleksandr Mosenkov
We compare eight sources of reddening and extinction estimates for approximately 60,000 {\it Gaia} DR1 Tycho--Gaia Astrometric Solution (TGAS) main sequence stars younger than 3~Gy…
Production, Processing and Consumption of the Dust in the Galaxy
George Gontcharov
The recent results obtained by the modern telescopes and spacecrafts allow us for the first time to compare directly the mass, spatial density and size distribution of the dust gra…
3D Reddening and Extinction Maps at the Beginning of the Gaia Era
George Gontcharov, Aleksandr Mosenkov
The vast majority of Gaia DR1 Tycho-Gaia astrometric solution (TGAS) stars are located within a distance of 1200 pc from the Sun and up to 600 pc within the Galactic plane. Complet…
Spatial Variations of the Interstellar Polarization and Interstellar Extinction
George Gontcharov
For more than 5000 stars with accurate parallaxes from the Hipparcos and Gaia DR1 Tycho-Gaia astrometric solution (TGAS), Tycho-2 photometry, interstellar polarization from eight c…
Systematic Error of the Gaia DR1 TGAS Parallaxes from Data for the Red Giant Clump
George Gontcharov
Based on the Gaia DR1 TGAS parallaxes and photometry from the Tycho-2, Gaia, 2MASS, and WISE catalogues, we have produced a sample of about 100 000 clump red giants within about 80…
Using the reduced proper motions of Tycho-2 stars with B-V from 0.75 to 1.25: Monte Carlo simulations
George Gontcharov
The stellar composition of the Tycho-2 Catalogue in the range has been reproduced through Monte Carlo simulations. For young and old stars of the red giant clump (R…
