Dwarf K and M stars of high proper motion found in a hemispheric survey.
Abstract
A recently completed visual/red spectral region objective-prism survey of more than half the sky found some 2200 dwarf K and M stars of negligible proper motion (Stephenson, 1986). The present paper adds the 1800-odd spectroscopically identified dwarfs that did prove to have significant proper motions. About half of these had previous spectral classifications of some sort, especially by Vyssotsky (1952, 1956). For the great majority, the present coordinates are more accurate than previous data. The paper includes about 50 stars with unpublished parallaxes, likely to have parallaxes of 0.05 arcsec or more. Combining the present data with the first paper suggests that the number of low-proper-motion stars in that paper was not unreasonable.
