摘要：

This catalog(1) provides an easy access to the basic astrophysical and dynamical characteristics of nearby (d < 25 pc) visual binary systems (pairs) in which at least one component is a UV Cet type flare star, It contains 138 such pairs (111 flare stars) of which 31 pairs have known orbital parameters. Along with parallax mainly (but not only) taken from SIMBAD, apparent and absolute magnitudes of each component, spectral types for all primaries and the vast majority of secondaries are given. On the basis of cataloged data, absolute brightness vs. spectral type and mass vs. spectral type relations for flare and non-flare stars are constructed. It is shown that flare and non-flare stars cannot be distinguished on the absolute brightness vs. spectral type plane. Comparison between photometric and dynamical masses suggests that photometric mass of flare stars can be estimated using the mass vs. absolute brightness relation of non-flare stars.
