Orientations of orbital planes of binaries

Abstract

Orientations of orbital planes of binaries are analyzed by using a complete sample of known orbital systems. The use of a so large sample is possible due to the application of a new procedure enabling to include the binaries for which the ascending nodes do not certain. It is concluded that generally, the distribution of observed orientations of the orbital planes does not differ from simulated random orientations. In both cases the same star positions are retained.
