Kinematics of RS CVn and W UMa binaries in the Hipparcos catalogue.

Yesilyaprak, C.; Özdemir, T.; Aslan, Z. +1 more

Space motions of RS CVn and W UMa binaries have been calculated using parallaxes and proper motions from Hipparcos catalogue and radial velocities from the literature. The authors have calculated the mean motions and velocity dispersions. They have excluded those binaries with relative parallax errors ≥0.5. The comparison of the asymmetric drift, …
