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.

Exact equatorial coordinates of known or new components of some 200 double or multiple systems
A catalog of binary and multiple star systems is being defined as aprelude to astrometric measurements scheduled for the Hipparchossatellite, which will be launched in 1988. Each system is beingphotographed twice to account for known and new components. Positivedeclinations are drawn from the AGK3 catalog, while the SAO catalogfurnishes the negative declinations. Mean square errors are beingcomputed for positions recorded in each of the photographs, yielding anumerical accuracy of 0.001 sec and 0.01 arcsec. The resulting data basewill contain the UNSO designation, the component types, the system name,the photographic magnitude, the spectrum, the observation epoch, theright ascension, the equinoctial declination, the angular position indegrees from the 2000.0 equinox, the recorded position, and remarks asto known features of the objects.
