Next generation spectroscopic analysis for large samples of massive stars [PDF]
Proc. IAU 18 (2022) 145-150, 2022 Upcoming large-scale spectroscopic surveys such as WEAVE and 4MOST will provide thousands of spectra of massive stars, which need to be analysed in an efficient and homogeneous way. Studies on massive stars are usually based on samples of a few hundred objects which pushes current spectroscopic analysis tools to their limits because visual inspection ...

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.

The Astrophysical Journal, 2023 We present the results of our Hubble Space Telescope far-ultraviolet survey of the blue lurkers (BLs) in M67. We find evidence for two white dwarf (WD) companions among the BLs that are indicative of mass transfer from an evolved companion, one in WOCS ...

The Astrophysical Journal Supplement Series, 2023 Double-line spectroscopic binaries (SB2s) are a vital class of spectroscopic binaries for studying star formation and evolution. Searching for SB2s has been a hot topic in astronomy.

A Spectroscopic Study of Field and Runaway OB Stars [PDF]
Astrophys.J.655:473-483,2007, 2006 Identifying binaries among runaway O- and B-type stars offers valuable insight into the evolution of open clusters and close binary stars. Here we present a spectroscopic investigation of 12 known or suspected binaries among field and runaway OB stars.

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 theEighth Catalogue of the Orbital Elements of Spectroscopic Binary Stars, compiled by Battenet al. (1989), are investigated. Histograms are presented of the distributions of various parameters of the systems in the catalogue as

The Astronomical Journal, 2023 While secondary mass inferences based on single-lined spectroscopic binary (SB1) solutions are subject to $\sin i$ degeneracies, this degeneracy can be lifted through the observations of eclipses.

The New Version of the Binary Star Database (BDB)
Open Astronomy, 2012 The Binary star database contains data on about 100 000 stellar systems of multiplicity 2 to 22, taken from a large variety of published catalogues for all types of binary stars: visual, orbital, astrometric, interferometric, spectroscopic, photometric ...

Discovery of the Exceptionally Short Period Ultracool Dwarf Binary LP 413-53AB
The Astrophysical Journal Letters, 2023 We report the detection of large-amplitude, rapid radial velocity (RV) variations and line-splitting in high-resolution Keck/NIRSPEC spectra of the M9 dwarf LP 413-53. We attribute these features to binary motion.

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.
