Statistical Investigation of Spectroscopic Binary Stars [PDF]
Symposium - International Astronomical Union, 1980 A catalog of physical parameters of about 1000 spectroscopic binary stars (SB), based on the Batten catalog, its extensions, and newly published data has been compiled. Masses of stars′ components (M1 and M2), mass ratios of components (q = M1/M2) and orbital angular momenta are computed, wherever possible. It is probable that the initial mass function

Statistical properties of spectroscopic binary stars [PDF]
Astrophysics and Space Science, 1992 As part of a study of the mass-ratio distribution of spectroscopic binary stars, the statistical properties of the systems in the Eighth Catalogue of the Orbital Elements of Spectroscopic Binary Stars, compiled by Batten et al. (1989), are investigated.

DOUBLE-LINED SPECTROSCOPIC BINARY STARS IN THE RAVE SURVEY [PDF]
The Astronomical Journal, 2010 We devise a new method for the detection of double-lined binary stars in a sample of the Radial Velocity Experiment (RAVE) survey spectra. The method is both tested against extensive simulations based on synthetic spectra and compared to direct visual inspection of all RAVE spectra.

A Spectroscopic Survey for Binary Stars in the Globular Cluster NGC 5053 [PDF]
The Astronomical Journal, 1996 We carried out a radial velocity survey for spectroscopic binaries in the low density globular cluster NGC5053. Our sample contains a total of 77 cluster member giant and subgiant stars with visual magnitudes of 14.5-18.6. Of these 77 stars, 66 stars have on average of 3-4 measurements with a total of 236 velocities.

Search for a Black Hole Binary in Gaia DR3 Astrometric Binary Stars with Spectroscopic Data
The Astrophysical Journal, 2023 We report the discovery of a candidate binary system consisting of a black hole (BH) and a red giant branch star in Gaia DR3. This binary system was discovered from 64,108 binary solutions for which both astrometric and spectroscopic data are available ...
