The Axial Zone of Avoidance in the Globular Cluster System and the Distance to the Galactic Center

I. I. Nikiforov, E. V. Agladze

We have checked the existence of a zone of avoidance oriented along the Galactic rotation axis in the globular cluster (GC) system of the Galaxy and performed a parametrization of…

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…
