Scientists have uncovered the existence of a binary star system close to the black hole near the center of the Milky Way galaxy, confirming a hypothesis made by happenstance nearly a century ago ...

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

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

One of them has yielded the first compelling evidence of a binary star system — called D9 — orbiting the galactic center. This pair of stars orbit each other about once a year. Based on the ...

The discovery, which relied on data from the European Southern Observatory’s Very Large Telescope, marks the first time that a binary star system has been observed in the vicinity of a ...

The lone planet confirmed to be in the system is squeezed in between the two, orbiting at a distance similar to Earth's distance from the Sun. And, as an added bonus, the planet is orbiting backward ...

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 ...

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 ...

A large team of astronomers and astrophysicists affiliated with several institutions in China has discovered a binary star system, where one of the stars is a millisecond pulsar and the other is ...

For the first time, astronomers have spotted a rapidly spinning neutron star that is gravitationally bound to a helium star companion. The discovery of this unusual binary system helps confirm a ...
