Binary stars as a research area encompass the observational, theoretical, and computational study of gravitationally bound stellar pairs, focusing on their formation, orbital dynamics, mass transfer, and evolutionary pathways. This field investigates how binarity affects stellar structure, nucleosynthesis, angular momentum evolution, and endpoints such as white dwarf, neutron star, or black hole binaries. It also includes characterization of spectroscopic, eclipsing, and astrometric binaries, derivation of fundamental stellar parameters from orbital solutions, and modeling of interaction phenomena such as accretion, common-envelope evolution, and mergers, which are crucial for understanding supernova progenitors, gravitational-wave sources, and the statistical properties of stellar populations.
For the first time, scientists have measured the instantaneous mind-blowing power of jets blasting from a black hole.

Astronomers from the South African Astronomical Observatory (SAAO) and elsewhere have conducted photometric and spectroscopic observations of a cataclysmic variable system designated SRGA J115215.0−510656. Results of the ...
Our sun is a bit of an outlier in the general stellar population. We typically think of stars as being solitary wanderers throughout the galaxy. But roughly half of sun-like stars are locked in with more than one companion ...

Using the Rozhen National Astronomical Observatory, Bulgarian astronomers have conducted optical photometric observations of an ultracompact binary known as GP Com. Results of the observational campaign, presented in the ...
Planets may actually form more easily around double stars than around single stars like our sun, according to new research from astrophysicists at the University of Lancashire. Binary stars are common in our galaxy, yet for ...

A star's mass determines its entire life story, from how it shines to how it dies. For young stars shrouded in dust, getting an accurate mass has long been difficult, but new radio measurements are beginning to change that. ...

Astronomers analyzing gravitational-wave data from the LIGO-Virgo-KAGRA Collaboration have reported that merging binary black holes fall into three distinct categories. The study shows that the three subpopulations have their ...
Utilizing the stellar evolution code named Modules for Experiments in Stellar Astrophysics (MESA), Chinese astronomers have investigated the evolution of a recently discovered ultra-compact double white dwarf binary system ...
Astronomers from the California Institute of Technology (Caltech) and elsewhere report the discovery of a binary system consisting of two brown dwarfs undergoing stable mass transfer. The detection of the system, designated ...
Visible to the naked eye in the constellation Cassiopeia, the star γ Cas has puzzled astrophysicists for half a century. It emits X-rays of an intensity and temperature incompatible with what one would expect from an ordinary ...
