Binary stars in the RAVE survey

open access: yesEPJ Web of Conferences, 2012
We searched the sample of RAVE survey spectra for both types of spectroscopic binary stars in order to estimate their number in the sample and perform a study on newly discovered binaries.

Fundamental effective temperature measurements for eclipsing binary stars – IV. Selection of new benchmark stars and first results for HD 22064 [PDF]

open access: yes, 2023
I describe the selection and initial characterization of 20 eclipsing binary stars that are suitable for calibration and testing of stellar models and data analysis algorithms used by the PLATO mission and spectroscopic surveys. The binary stars selected

A survey for low mass spectroscopic binary stars in the young clusters around sigma Orionis and lambda Orionis [PDF]

open access: yes, 2008
We have obtained multi-epoch, high-resolution spectroscopy of 218 candidate low-mass stars and brown dwarfs in the young clusters around sigma Ori and lambda Ori. We find that 196 targets are cluster members based on their radial velocity, the equivalent

New spectroscopic binary companions of giant stars and updated metallicity distribution for binary systems [PDF]

open access: yes, 2016
We report the discovery of 24 spectroscopic binary companions to giant stars. We fully constrain the orbital solution for 6 of these systems. We cannot unambiguously derive the orbital elements for the remaining stars because the phase coverage is ...

The GALAH survey: multiple stars and our Galaxy [PDF]

open access: yes, 2020
Context. Binary stellar systems form a large fraction of the Galaxy’s stars. They are useful as laboratories for studying the physical processes taking place within stars, and must be correctly taken into account when observations of stars are used to ...

EL CVn-type binaries - discovery of 17 helium white dwarf precursors in bright eclipsing binary star systems [PDF]

open access: yes, 2014
The star 1SWASP J024743.37−251549.2 was recently discovered to be a binary star in which an A-type dwarf star eclipses the remnant of a disrupted red giant star (WASP 0247−25 B).

The effect of tides on near-core rotation: analysis of 35 Kepler γ Doradus stars in eclipsing and spectroscopic binaries [PDF]

open access: yes, 2020
We systematically searched for gravity- and Rossby-mode period spacing patterns in Kepler eclipsing binaries with γ Doradus pulsators. These stars provide an excellent opportunity to test the theory of tidal synchronization and angular momentum transport

The CARMENES search for exoplanets around M dwarfs. Nine new double-line spectroscopic binary stars [PDF]

open access: yes, 2018
Context. The CARMENES spectrograph is surveying ̃300 M dwarf stars in search for exoplanets. Among the target stars, spectroscopic binary systems have been discovered, which can be used to measure fundamental properties of stars.

Eclipsing binaries observed with the WIRE satellite. II, β Aurigae and non-linear limb darkening in light curves [PDF]

open access: yes, 2007
Aims. We present the most precise light curve ever obtained of a detached eclipsing binary star and use it investigate the inclusion of non-linear limb darkening laws in light curve models of eclipsing binaries.

Mining Double-line Spectroscopic Candidates in the LAMOST Medium-resolution Spectroscopic Survey Using a Human–AI Hybrid Method

open access: yesThe Astrophysical Journal Supplement Series
We utilize a hybrid approach that integrates the traditional cross-correlation function (CCF) and machine learning to detect spectroscopic multiple star systems, specifically focusing on double-line spectroscopic binaries (SB2s).
