Chinese astronomers have employed NASA's Transiting Exoplanet Survey Satellite (TESS) to observe an eclipsing binary of the ...

Binary neutron star mergers, cosmic collisions between two very dense stellar remnants made up predominantly of neutrons, ...

A repeating radio burst every 2 hours from Ursa Major reveals a unique white dwarf–red dwarf system, shaking up theories in ...

Astronomers in China have observed a pulsar that becomes partially eclipsed by an orbiting companion star every few hours.

Get Instant Summarized Text (Gist) A binary star system has been identified consisting of a millisecond pulsar and a helium-rich companion star with a mass between 1 and 1.6 M☉ ...

In a stunning peek into how planets are born, astronomers caught millimeter-sized dust grains clinging to the windy walls of ...

Astronomers have identified a rare type of binary star system containing a rapidly spinning millisecond pulsar and a helium star companion, formed via common envelope evolution. Although such ...

To address this difficulty, astrophysicists from Villanova drafted in artificial intelligence (AI) in the hope that it could take what appears to be a single point of stellar light in systems many ...

Binary star systems, or pairs of stars that orbit around each other, are very common. In fact, it’s estimated that 85% of stars in the universe have at least one companion.

The stars in a binary can vary widely in mass, size, and brightness, and their interactions often shape their evolution in dramatic ways. In some cases, the gravity from one star can drag material ...

Astronomers may have discovered a rare type of binary star system, where one star used to orbit inside its partner. In the new study, astronomers investigated a pulsar known as PSR J1928+1815 ...
