Observations of a pulsar, consisting of a dead star spinning 600 times a second, and feasting on a stellar companion reveal ...

Only a few dozen of these short-lived binaries exist in the galaxy at a time, making the serendipitous find extremely ...

Binary neutron star mergers, cosmic collisions between two very dense stellar remnants made up predominantly of neutrons, have been the topic of numerous astrophysics studies due to their ...

As binary neutron stars inspiral for millions of years, they emit gravitational waves, but the most intense emission occurs at and just milliseconds after the moment of merging.

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 ...

Overall, the simulations performed by Müller, Heger and Powell suggest that the low-mass star in the binary system J0453 + 1559 could in fact be a neutron star.

Astronomers have discovered 21 "one in a million" binary systems in which sun-like stars orbit a hidden "dead star," an extreme dense and compact object called a neutron star.

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 ...

“Black widow” neutron star devoured its mate to become heaviest found yet This work may set an upper limit on just how large neutron stars can become.

Binary neutron star mergers occur millions of light-years away from Earth. Interpreting the gravitational waves they produce presents a major challenge for traditional data-analysis methods. These ...

Astronomers show how a neutron star ended in a dud supernova, and shed light on the system's history, evolution, and atypically calm stellar death.

Binary neutron star mergers, cosmic collisions between two very dense stellar remnants made up predominantly of neutrons, have been the topic of numerous astrophysics studies due to their ...
