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.
Astronomers from Australia and Serbia have performed multi-band photometric observations of a binary star known as V717 Andromedae. The observations yielded crucial information regarding the properties of V717 Andromedae, ...
Researchers from the Yunnan Observatories of the Chinese Academy of Sciences (CAS) have unveiled a neural network-based automated method for identifying heartbeat stars—a rare type of binary star system. Their findings are ...

Manuel Linares is a physicist at NTNU who studies binary stars called "spider pulsars." The stars got this name because they could eat their partner, just like some spiders do.

An international team of astronomers reports the discovery of a new "spider" millisecond pulsar, which received designation PSR J1544−2555. The finding was presented in a research paper published September 11 on the arXivpre-print ...
Binary star systems are not rare. Neither are systems where one star is a remnant like a white dwarf or neutron star, and its companion is on the main sequence. In those systems, the dense remnant can draw material away from ...

An international team of astronomers reports the discovery of a new pre-main-sequence eclipsing binary system. The newfound binary, designated MML 48, consists of two young low-mass stars. The finding will be published in ...
A greedy white dwarf star not far from Earth is devouring its closest celestial companion at a rate never seen before, space scientists have discovered. Their study found the double star, named V Sagittae, is burning unusually ...

Using the Hubble Space Telescope (HST), Italian astronomers have observed five blue straggler stars in the globular cluster 47 Tucanae. Their results show that one of these stars has a white dwarf companion. The discovery ...
Using ESA's INTEGRAL spacecraft, astronomers have detected exceptionally bright X-ray flares from the Cygnus X-1 X-ray binary system. This is the first time that such strong flaring activity has been observed in this system ...
Massive stars in metal-poor galaxies often have close partners, just like the massive stars in our metal-rich Milky Way. This was discovered by an international team of 70 astronomers led by scientists from Belgium, the Netherlands, ...
