The JKT scanning slits : investigating binary stars.
Not Available

Orbital binaries with variable components
Published observational data are compiled for 171 binary systems forwhich (1) orbital parameters have been computed and (2) one or bothcomponents are known or suspected to exhibit intrinsic variability. Theselection criteria for the catalog are discussed; the data are presentedin a large table; and brief notes on the unusual characteristics ofspecific binaries are provided.

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.
