Photographic Astrometry of Binary and Proper-Motion Stars. V.
Abstract
In the study of dwarf star distances and of binary-star masses at the 61-cm Swarthmore refractor, parallaxes of 69 stars and systems were obtained by processing some 5000 astrometric plates from April 1988 to July 1989. These results are listed along with 11 binary-star mass ratios and three unresolved pairs.
