The statistical distribution of the total mass of 14 double neutron star (DNS) systems (out of 18 pairs observed) is found to be very narrow, with the average and standard deviation as 2.65 ± 0.03 M☉.

Neutron stars are ultra-dense star remnants made up primarily of nucleons (i.e., protons and neutrons). Over the course of ...

Neutron stars are some of the weirdest cosmic objects, and the greatest mysteries lie deep in their hearts. Neutron stars are the leftover cores of exploded stars and the densest known material in the ...

Neutron stars are covered with "mountains" only fractions of a millimeter tall, new research shows, meaning these bumps are hundreds of times smaller than previous estimates had suggested. Now, new ...

Neutron stars are incredibly dense, city-sized remnants of massive stars. They form after a supernova when gravity overcomes electron degeneracy pressure. Some neutron stars, called pulsars, emit ...

Physicists have measured the microscopically thin skin of neutrons enclosing the insides of atoms of lead for the first time, finding that it's thicker than expected. The discovery could help to ...

When a massive star dies in a supernova, the explosion is only the beginning of the end. Most of the stellar matter is thrown far and wide, but the star’s iron-filled heart remains behind. This core ...

The heaviest neutron star ever detected is shredding its companion while spinning on its axis over 700 times per second. The neutron star, known as PSR J0952-0607, was discovered in 2017 about 3,000 ...
