Binary Central Stars of Planetary Nebulae Discovered Through Photometric Variability. III. The Central Star of Abell 65 [PDF]
, 2015 A growing number of close binary stars are being discovered among central stars of planetary nebulae. Recent and ongoing surveys are finding new systems and contributing to our knowledge of the evolution of close binary systems.

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 White Dwarf Binary Pathways Survey – IV. Three close white dwarf binaries with G-type secondary stars [PDF]
, 2020 Constraints from surveys of post common envelope binaries (PCEBs) consisting of a white dwarf plus an M-dwarf companion have led to significant progress in our understanding of the formation of close white dwarf binary stars with low-mass companions. The

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

Close binary central stars and the abundance discrepancy - new extreme objects [PDF]
Proceedings of the International Astronomical Union, 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 ...

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.

Tidally trapped pulsations in a close binary star system discovered by TESS [PDF]
Nature Astronomy, 2020 It has long been suspected that tidal forces in close binary stars could modify the orientation of the pulsation axis of the constituent stars. Such stars have been searched for, but until now never detected.

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.

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
