The evolution of massive binary systems [PDF]
Serbian Astronomical Journal, 2020 The evolution of massive stars in close binary systems is significantly different from single star evolution due to a series of interactions between the two stellar components.

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.

Fast rotating stars resulting from binary evolution will often appear to be single [PDF]
, 2010 Rapidly rotating stars are readily produced in binary systems. An accreting star in a binary system can be spun up by mass accretion and quickly approach the break-up limit.

The Evolution of the Supersoft X-Ray Source WX Cen Dominated by Magnetic Wind
The Astrophysical Journal, 2023 WX Cen is most likely one of the Galactic counterparts of compact binary supersoft X-ray sources as a member of the V Sagittae class, in which mass is transferred from a donor secondary to a massive white dwarf primary via an accretion disk. Based on the

Multifilter Time-series Observations of Eleven Blue Short-period ATLAS Variable Stars
The Astronomical Journal, 2023 Eleven periodic variable stars were observed photometrically through two to four filters from the set UBVR _C I _C . Phase-folded data for each star cover full cycles of variation.

From a Dinuclear System to Close Binary Cosmic Objects
Astronomy, 2023 Applying the ideas from microscopic objects to macroscopic stellar and galactic systems, the evolution of compact di-stars and di-galaxies is studied in the mass asymmetry coordinate. The formation of stable binary systems is analyzed.

Asteroseismic effects in close binary stars [PDF]
, 2013 Turbulent processes in the convective envelopes of the sun and stars have been shown to be a source of internal acoustic excitations. In single stars, acoustic waves having frequencies below a certain cutoff frequency propagate nearly adiabatically and ...

POSYDON: A General-purpose Population Synthesis Code with Detailed Binary-evolution Simulations
The Astrophysical Journal Supplement Series, 2023 Most massive stars are members of a binary or a higher-order stellar system, where the presence of a binary companion can decisively alter their evolution via binary interactions. Interacting binaries are also important astrophysical laboratories for the

COMMISSION 42: CLOSE BINARY STARS [PDF]
Proceedings of the International Astronomical Union, 2011 The present report covers the main developments in the field of close binaries during the triennium 2009-2012. In addition to scientific publications, there have been several opportunities for direct interaction of researchers working on close binaries. A number of meetings focused on more or less specific topics have taken place during this past years
