| Abstract: | A comparison is made between the velocity distribution of 106 dMe stars and 202 M dwarfs whose spectra are not known to show any emission. The data used are free from selection effects. The solar velocity is 13 km/sec relative to the dMe stars and 23 km/sec relative to the dM stars. Velocity dispersion and number of high velocities are considerably smaller in the dMe group than in the dM group. The dMe stars show a vertex deviation of about 10 deg - 20 deg. This investigation demonstrates that marked differences exist in the kinematical behaviour of both groups. Asymmetry is present in both of them. |
