The LIGO/VIRGO/KAGRA collaboration searches the universe for gravitational waves produced by the mergers of black holes and neutron stars. It has now announced the detection of a signal indicating a ...

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

An important breakthrough in how we can understand dead star collisions and the expansion of the Universe has been made by an international team, led by the University of East Anglia. They have ...

Some of the densest objects in the universe are neutron stars. Neutron stars are the remnants of stellar cores left behind when a star has gone supernova. The only known objects denser than neutron ...

Scientists have precisely measured two unstable atomic nuclei that play a crucial role in explosive X-ray bursts on neutron ...

Researchers at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) and their collaborators recently measured the masses of several key nuclei with high-precision by ...

Electron-capture supernovae (ECSNe) are stellar explosions that occur in stars with initial masses around 8–10 times that of the sun. These stars develop oxygen-neon-magnesium cores, which become ...

WASHINGTON, July 29 (Reuters) - Astronomers have observed the most massive known example of an object called a neutron star, one classified as a "black widow" that got particularly hefty by gobbling ...

Astronomers have determined the heaviest neutron star known to date, weighing in at 2.35 solar masses, according to a recent paper published in the Astrophysical Journal Letters. How did it get so ...

Paul D. Lasky is in the School of Physics and Astronomy, Monash University, Melbourne 3800, Australia. Nuclear physicists cannot calculate how matter should behave during and immediately after these ...
