The kinematics of OB-stars and Cepheids based on Gaia DR2 catalogue

Abstract

The purpose of the work was to study the kinematics and refine the distance scale of young objects of the galactic disk: OB stars and high-luminosity stars of late spectral classes, as well as Cepheids. We used the observational data obtained during the Gaia mission and published in the Gaia DR2 catalog. The statistical parallax method was used to determine the kinematic parameters of objects.
