Abstract Racial velocities have been determined for 56 stars of large proper motion. Of these, 2 are white dwarfs, 35 are subdwarf s, and 19 are main-sequence stars. New spectral types have been derived for all stars except the M dwarfs and the white dwarfs. For these Kuiper's spectral types have been adopted. Five M dwarfs have been found to have the calcium lines H and K in emission Publication: The Astrophysical Journal Pub Date: March 1942 DOI: 10.1086/144397 Bibcode: 1942ApJ....95..307P full text sources ADS |
