Dynamical origin of S-type planets in close binary stars [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Understanding the origin of planets that have formed in binary stars is fundamental to constrain theories of binary and planet formation. The planet occurrence rate in binaries with a separation $\lesssim 50$ AU is only $\sim$ one third that of wider ...

Disks in close binary stars [PDF]
Astronomy & Astrophysics, 2021 Context. Close binaries (abin ≤ 20 au) are known to harbor planets, yet planet formation is unlikely to succeed in such systems. Studying the dynamics of disks in close binaries can help to understand how those planets could have formed. Aims. We study the impact that numerical and physical parameters have on the dynamics of disks in close binaries. We

From dinuclear systems to close binary stars: Application to source of energy in the universe [PDF]
International Journal of Modern Physics E, 2018 The evolution of close binary stars in mass asymmetry (transfer) coordinate is considered. The conditions for the formation of stable symmetric binary stars are analyzed.

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

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.

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 ...

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.
