Abstract:
The kinematics of 129 W Ursae Majoris type binaries (W UMas) were
studied. The sample is heterogeneous with different orbits and
physically different components from F to K spectral-type
main-sequence stars. The computed U, V, W space velocities indicate
that the sample is also heterogeneous in velocity space.
