Abstract
ABSTRACT ADS 9193 was first cataloged as a visual binary by Herschel (1831), who reported a position angle of 165 deg and a separation of 5 arcsec for the system. Additional measurements up through 1966 have revealed little substantive change in these parameters. Optical spectra and UBV magnitudes obtained for both components of ADS 9193, as well as direct CCD image of the field containing these stars, confirm the previous findings for the astrometric characteristics of ADS 9193, and establish the spectral types of components A and B as M6/7 and F6, respectively. Although the probability that ADS 9193 is an optical double is low, the observed V magnitude difference is only half what would be expected if the stars are at a common distance of approximately 200 pc, assuming the primary is a giant and its companion is on the main sequence.
