Observational Selection in Spectroscopic Binary Eccentricities

Part of the Astrophysics and Space Science Library book series (ASSL, volume 98)


The discovery-and-identification probability for different shaped orbits of spectroscopic binary stars is estimated. The eccentricity distribution observed in the sample of ∼1000 binaries with known orbits and appearing as strongly peaked toward e=0 is corrected for observational selection effects. The resulting e-distribution seems to be flat for e in the range ∼0.05–0.6 with some excess of circular (or almost circular) orbits and a deficiency of orbits with e ≳ 0.6.
