Kinematics of RS CVn and W UMa Binaries in the Hipparcos Catalogue
RS CVn W UMa Binaries Hipparcos Catalogue
2010/4/16
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. We have calculating the mean mot...
Short-period RS CVn and W UMa binaries: how are they related?
W Ursae Majoris angular momentum loss
2010/4/16
Two groups of late-type very close main sequence binaries, the so-called short-period RS Canum Venaticorum (RS CVn) and W Ursae Majoris (W UMa) systems, are important for the understanding of the stru...
