Physicists at Goethe University in Frankfurt, Germany, have used supercomputer simulations to predict a specific gravitational-wave fingerprint that would confirm quark-gluon plasma forms inside the ...

As binary neutron stars spiral around each other to merge, their gravitational tidal forces distort each other's shape and ...

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of ...

A new theoretical framework shows that tidal forces in inspiraling neutron star pairs can be described through oscillation modes, opening a new path to studying ultra-dense matter using gravitational ...

A newly analyzed gravitational-wave event has revealed something unexpected about one of the Universe’s most violent encounters. Scientists have found the first strong evidence that a black hole and a ...

Using the Hard X-ray Modulation Telescope (HXMT) and the Neutron star Interior Composition Explorer (NICER), astronomers from China and India have observed two X-ray binaries known as GX 339−4 and EXO ...

Astronomers using ESA’s gamma-ray observatory, Integral, have detected what appears to be the fastest spinning neutron star yet. This tiny stellar corpse is spinning 1122 times every second. If ...

How fast can a neutron star spin? This is what a recent study published in The Astrophysical Journal hopes to address as an international team of more than a dozen researchers have identified one of ...

Astronomers studying archival observations of powerful explosions called short gamma-ray bursts (GRBs) have detected light patterns indicating the brief existence of a superheavy neutron star shortly ...
