Bobylev, V. V.; Bajkova, A. T.; Tsvetkov, A. S. +1 more

The three-dimensional velocities of stars with high-precision positions, proper motions, and parallaxes from the Gaia TGAS catalog and radial velocities from the RAVE5 catalog are examined. A sample of 92395 stars with estimated ages yields the following kinematic parameters: (U, V, W)=(9.42, 20.34, 7.21)±(0.12, 0.10, 0.09) km/s, Ω = 26.29 ± 0.39 …
