Radial Velocities of Proper-Motion Stars.
Abstract
Radial velocities have been determined for 39 stars of large proper motion. New spectral types are given, except for the M dwarfs and the white dwarfs. For these, Kuiper's spectral types have been adopted. Three dwarfs have the H and K lines of Ca ii in emission, and one of these (BD+55 °1823, Ml) also shows the hydrogen lines in emission
