A tiny, dense stellar corpse in a nearby galaxy is pumping out so much energy that, on paper, it should have blown itself ...

The blast may have been a kilonova — a type of neutron star merger — in the wake of a more traditional supernova.

Astronomers have weighed a neutron star with nearly double the mass of the sun, the heaviest yet found. A mass that high rules out many theories that these ultradense remnants of supernova explosions ...

A: The quick answer to your question is yes, they can gain matter. However, only a small fraction of neutron stars can gain mass — those in binary systems, where mass is transferred from the companion ...

Scientists have precisely measured two unstable atomic nuclei that play a crucial role in explosive X-ray bursts on neutron stars. The results reveal faster nuclear reactions than previously thought, ...

Astrophysicists are closing in on one of the strangest possibilities in stellar evolution, a compact remnant that might sit ...

Massive merger: illustration of gravitational waves from a neutron-star merger Data from the recent observation of gravitational waves from the merger of a binary neutron star have been used to place ...
