Chromospherically active binaries members of young stellar kinematic groups

Astrophysics 2016-08-30 v1

Abstract

We present a kinematic study of a large sample of chromospherically active binaries (CAB) in order to determine their membership to representative young disk stellar kinematic groups: the Local Association (Pleiades moving group, 20 - 150 Myr), Ursa Mayor group (Sirius supercluster, 300 Myr), Hyades supercluster (800 Myr), IC 2391 supercluster (35 Myr) and Castor moving group (200 Myr). Precise measurements of proper motions and parallaxes taken from Hipparcos Catalogue and published radial velocity measurements are used to calculate Galactic space motions (U, V, W) in order to determine the membership of the selected stars to the different stellar kinematic groups.
