Masses and angular momenta of contact binary stars [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2006 Abstract Results are presented on component masses and system angular momenta for over 100 low-temperature contact binaries. It is found that the secondary components in close binary systems are very similar in mass. Our observational evidence strongly supports the argument that the evolutionary process goes from near-contact binaries to

Contact binary stars. I - an X-ray survey
Astrophysical Journal, 1984 X-ray emission from a contact binary star was first detected by the HEAO 1 satellite in 1977. Spectroscopic observations of 44i Boo and VW Cep by IUE established the presence of high-temperature chromospheric and transition region emission lines in the spectra of these stars.

Space-Based Photometry of Binary Stars: From Voyager to TESS [PDF]
Universe, 2021 Binary stars are crucial laboratories for stellar physics, so have been photometric targets for space missions beginning with the very first orbiting telescope (OAO-2) launched in 1968.

Microwave emission from southern contact-binary stars
Astronomical Journal, 1993 We report the results of high-sensitivity 4.8 GHz observations of four southern contact-binary stars (AE Phe, YY Eri, RW Dor, and V757 Cen) made with the Australia Telescope Compact Array. None of these stars were detected above a 4σ level of 0.4 mJy.

Modelling of W UMa-type variable stars [PDF]
South African Journal of Science, 2009 W Ursae Majoris (W UMa)-type variable stars are over-contact eclipsing binary stars. To understand how these systems form and evolve requires observations spanning many years, followed by detailed models of as many of them as possible.

Investigation of a W UMa-type contact binary GZ And in a physical triple system
Frontiers in Astronomy and Space SciencesGZ And is a variable star within the visually observed multiple-star system ADS 1693. Recent observations have yielded new light curves for GZ And, obtained using the Xinglong 85-cm telescope and the Transiting Exoplanet Survey Satellite (TESS) satellite.

An Estimate of the Binary Star Fraction among Young Stars at the Galactic Center: Possible Evidence of a Radial Dependence [PDF]
The Astrophysical JournalWe present the first estimate of the intrinsic binary fraction of young stars across the central ≈0.4 pc surrounding the supermassive black hole (SMBH) at the Milky Way Galactic center (GC).
