Photometry of faint red stars Broadband photoelectric BVI photometry has been obtained for 56 redstars detected in an objective-prism survey. The magnitude range for theprogram stars was V = 8.6-12.2. The sample contained 33 probable dwarfstars and 21 probable giant stars identified using the (B-V) - (V-I)two-color diagram and two stars of uncertain luminosity class. Distanceswere derived from photometric parallaxes and used with proper motionsobtained from various sources to compute tangential velocities for theprobable dwarf stars.
| Dwarf K and M stars of small proper motion found in a large spectroscopic survey More than 2000 candidates for K and M dwarf status, generally havingproper motions that are either unknown or less than 0.2 arcsec perannum, have been identified in an objective-prism survey covering theentire sky north of declination - 25 degrees and more than 10 degreesfrom the galactic plane. More than 95 percent have no previousindication that they are dwarfs. Several dozen appear to be visualdouble stars.
