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.
Eventually, every stellar civilization will have to migrate to a different star. The habitable zone around all stars changes as they age. If long-lived technological civilizations are even plausible in our universe, migration ...

Many black holes detected to date appear to be part of a pair. These binary systems comprise a black hole and a secondary object—such as a star, a much denser neutron star, or another black hole—that spiral around each other, ...

Russian astronomer Valerij Kozhevnikov has performed photometric observations of a candidate cataclysmic variable known as LAMOST J035913.61+405035.0. He detected 14 eclipses of this system. The finding was reported in a ...
The background noise of gravitational waves from orbiting white dwarf stars will be stronger than the noise from binary black holes. This is what two Dutch master's students and their supervisor predict in two papers in anticipation ...
