Binary stars are as common as single stars. Binary stars are of immense importance to
astrophysicists because that they allow us to determine the masses of the stars independent …

Population-synthesis codes are an unique tool to explore the parameter space of massive
binary star evolution and binary compact object (BCO) formation. Most population-synthesis …

Common envelope (CE) evolution, which is crucial in creating short-period binaries and
associated astrophysical events, can be constrained by reverse modelling of such binaries' …

Context. About a third of the hot subdwarfs of spectral type B (sdBs), which are mostly core-
helium-burning objects on the extreme horizontal branch, are found in close binaries with …

Binary stars are responsible for many unusual astrophysical phenomena, including some
important explosive cosmic events. The stability criteria for rapid mass transfer and common …

Virtually all binaries consisting of a white dwarf with a non-degenerate companion can be
classified as either close post-interaction systems (with orbital periods of a few days or less) …

Common envelope evolution (CEE) is vital for forming short-orbital-period compact binaries.
It covers many objects, such as double compact merging binaries, Type Ia supernovae …

Context. Hot subdwarfs in close binaries with either M dwarf, brown dwarf, or white dwarf
companions show unique light variations. In hot subdwarf binaries with M dwarf or brown …

Context. It has been claimed for more than a decade that energies other than orbital and
thermodynamic internal are required to explain post-common envelope (CE) binaries with …

Double white dwarf systems are of great astrophysical importance in the field of gravitational
wave and Type Ia supernova. While the binary fraction of CO core white dwarf is about a few …
