Close-in companions to contact binary stars [PDF]
, 2014 W UMa-type contact binaries are composed of two late-type main-sequence stars, where both components are filling their critical Roche Lobes and sharing a common convective envelope.

Super slowly spinning stars in close binaries
Monthly Notices of the Royal Astronomical Society: Letters, 2023 ABSTRACT Stars in short-period binaries typically have spins that are aligned and synchronized with the orbit of their companion. In triple systems, however, the combination of spin and orbital precession can cause the star’s rotation to evolve to a highly misaligned and sub-synchronous equilibrium known as a Cassini state. We identify a

Transactions of the International Astronomical Union, 1985 Research on close binary systems has continued at a high level during the past triennium, although the rate of growth is noticeably slower – probably reflecting the cutbacks in funds to which many of us are subject. There have also been changes of emphasis within the field, which are commented on in the pages that follow.

CLOSE BINARY SYSTEMS ON LATE EVOLUTIONARY STAGES
Odessa Astronomical Publications, 2017 Observational and theoretical progress in investigations of close binary stars allow to understand the nature and evolution of many types of close binary systems containing peculiar components: Wolf-Rayet stars, white dwarfs neutron stars and black holes.

Observations of binary stars with the differential speckle survey instrument. IV. Observations of Kepler, CoRoT, and Hipparcos stars from the Gemini North Telescope [PDF]
, 2012 We present the results of 71 speckle observations of binary and unresolved stars, most of which were observed with the DSSI speckle camera at the Gemini North Telescope in 2012 July. The main purpose of the run was to obtain diffraction-limited images of

Close binary central stars and the abundance discrepancy - new extreme objects [PDF]
, 2016 Recent work (Corradi et al. 2015, Jones et al. 2016) has shown that the phenomenon of extreme abundance discrepancies, where recombination line abundances exceed collisionally excited line abundances by factors of 10 or more, seem to be strongly ...

The Astrophysical Journal, 2023 We present a timing study of the short-period eclipsing cataclysmic variable (CV) HT Cas. Based on new eclipse times derived from our photometric monitoring and archival optical data, combined with historical timings, spanning ∼42 yr, we detect a secular
