Abstract:
The kinematics of 237 chromospherically active binaries (CABs) were
studied. The sample is heterogeneous with different orbits and
physically different components from F to M spectral-type
main-sequence stars to G and K giants and supergiants. The computed
U, V, W space velocities indicate that the sample is also
heterogeneous in velocity space.
