The MK Spectral Classification of Components of Binary and Triple Stars

The radial velocities of triple-star components
The paper presents 60 radial velocity measurements for 38 components of22 triple stars. Information is provided on the radial velocities of thetriple-star systems ADS 48,9716,9909 + + 9910, 10058, 11853 and of atriple star with alpha (1950) = 18 h 45 min, and delta (1950) = + 28 deg22 arcmin.

Photoelectric UBV-photometry of triple-star components
Photoelectric UBV photometry was performed on components of 30 brightand nearby triple stars to identify physically linked triple systems andto determine their distances and dynamic evolution. An analysis of 60catalogs showed only 10 triple systems. For every component, E(B-V) andE(U-B) color excesses are determined and photometric parallaxes arecalculated using available spectral types.

New UBVRI photometry for 900 supergiants
A description is presented of the results obtained in connection with asystematic program of supergiant photometry on the Johnson UBVRI system.During the eight years after the start of the program, almost 1000 starshave been observed, about 400 three or more times each. The originalselection of stars used the spectral type catalog of Jaschek et al.(1964) to choose supergiants. Since observations were possible from bothChile and Canada, no declination limits were imposed, and no particularselection criteria were imposed other than to eliminate carbon stars.These are so red as to require enormous extrapolations of thetransformation equations.
