Single-lined Spectroscopic Binary Star Candidates in the RAVE Survey [PDF]

open access: yesThe Astronomical Journal, 2011
Repeated spectroscopic observations of stars in the Radial Velocity Experiment (RAVE) database are used to identify and examine single-lined binary (SB1) candidates.

Binary Star Orbits. VI. The Interferometric-spectroscopic Binary 73 Leo

open access: yesThe Astronomical Journal
Discordances in radial-velocity measurements of 73 Leonis, made more than a century ago, gave rise to the first suggestion that this fifth-magnitude star was a binary system, but it was 40 yr before an accurate investigation of the object commenced, and ...

New spectroscopic binaries among nearby stars [PDF]

open access: yesAstronomy & Astrophysics, 2003
In the course of surveying a large number of nearby ( ≈ 50 pc or less) stars for indicators of youth, we have discovered a number of hitherto unknown spectroscopic binaries. Here we present a list of these new binaries with pertinent data. Two of these (HD 143705 and HD 89959) have been observed six times each, and their respective radial velocity ...

Statistical Investigation of Spectroscopic Binary Stars [PDF]

open access: yesSymposium - 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

Asteroseismology of binary stars and a compilation of core overshoot and rotational frequency values of OB stars [PDF]

open access: yes, 2013
After a brief introduction into the asteroseismic modelling of stars, we provide a compilation of the current seismic estimates of the core overshooting parameter and of the rotational frequency of single and binary massive stars. These important stellar

Spectroscopic Orbits of Subsystems in Multiple Stars. X (Summary)

open access: yesThe Astronomical Journal, 2023
Results of a large program of spectroscopic monitoring of nearby solar-type stellar hierarchical systems using the CHIRON echelle spectrograph at the 1.5 m telescope are summarized.

Statistical properties of spectroscopic binary stars [PDF]

open access: yesAstrophysics 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.

The Hot R Coronae Borealis Star DY Centauri is a Binary [PDF]

open access: yes, 2012
The remarkable hot R Coronae Borealis (RCB) star DY Cen is revealed to be the first and only binary system to be found among the RCB stars and their likely relatives, including the extreme helium stars and the hydrogen-deficient carbon stars.

AGB stars in binaries and their progeny [PDF]

open access: yes, 1998
It is currently admitted that an AGB star in a binary system is likely to pollute its companion with carbon- and s-process-rich matter. After the AGB star has faded into an unconspicuous white dwarf, the polluted companion enters the zoo of stars with ...
