UBVRI photometry of FKSZ stars. III
UBVRI photometry in the Kron-Cousins system is presented for 118 starsin the Catalogue of Fundamental Faint Stars (Zverev, 1957) in thedeclination zone between -60 and -90 degrees. The observations were madebetween September, 1984 and March, 1987 at the European SouthernObservatory at La Silla, Chile. Tables of the photometric data aregiven, including star number, V magnitude, spectral types, and (B-V),(U-B), (V-R), and (R-I) color indices.
| A catalog of chromospherically active binary stars
A catalog of 168 chromospherically active binary stars is presented,including the class of RS CVn, BY Dra binaries, and other binaries whichshow strong Ca II H and K emission in their spectra. The catalogcontains information on the photometric, spectroscopic, orbital, andphysical properties of the systems as well as the space motions andpositions. Summarized in a candidate list are in additional 37 starshaving similar characteristics but which are not definitely knownbinaries or have not had H and K emission observed. The catalog containsstars in both the northern and the southern sky.
