Caltech simulations reveal what happens when black holes collide with neutron stars—violent cracking, intense shock waves, ...

In a recent study, researchers used neutron star observations to infer the properties of quark matter at even higher densities where it is certain to be a color superconductor.

A neutron star's final moments may spark violent starquakes, monster shock waves, and even a fleeting, never-before-seen object called a black hole pulsar.

This color evolution is a telltale signature of a kilonova, and kilonovae can only come from neutron star mergers.” Kilonovas are rare, ...

It wasn’t until the 1960s that Zwicky and Baade’s hypothetical neutron stars were finally detected. Radio astronomer Jocelyn Bell Burnell noticed a strange, regularly pulsed radio wave signal ...

A dense, collapsed star spinning 707 times per second—making it one of the fastest spinning neutron stars in the Milky Way galaxy—has shredded and consumed nearly the entire mass of its ...
