The first-known supermassive black holes responsible for feeding on a Copernican star from a wide binary has been unearthed.

Neutron stars represent one of the final evolutionary stages of a massive star, forming when stars with at least eight times ...

Gliese 229 B, discovered in 1995, is a binary system of two brown dwarfs orbiting each other, in orbit around their parent red dwarf star.

that circle one another every 12 days as they orbit their sun every few hundred years. We sought to test whether Gliese 229 B is a brown dwarf binary. To evade astronomers’ notice for 30 years ...

In the binary system 4U 1820-30, a neutron star is spinning so fast around its center axis that it completes a breathtaking ...

Astronomers have stumbled upon something truly remarkable: a black hole that's not just part of a binary system, but part of ...

A third, tenuously held companion to the known binary V404 Cygni may signal that at least some black holes form "gently." ...

Astronomers discover a neutron star spinning 716 times per second, making it one of the fastest stars ever recorded.

There's evidence out there for the supernova model of black hole formation. This is when a dying star erupts in a colossal explosion, ejecting its outer material, while the core of the star collapses ...

The neutron star is part of an X-ray binary star system. Such a system consists of two stars orbiting each other. What is also peculiar with the system '4U 1820-30' is that the companion star is a ...
