Physicists have shown that extremely light particles known as axions may occur in large clouds around neutron stars. These axions could form an explanation for the elusive dark matter that ...

"Measuring the properties of neutron-star matter is indeed very hard and this is because while we can measure the mass of a neutron star very accurately, it is very hard to measure its radius ...

Neutron stars are some of the weirdest cosmic objects, and the greatest mysteries lie deep in their hearts. Neutron stars' surface gravities are so intense that the largest "mountains" are only a few ...

Neutron stars are ultra-dense star remnants made up primarily of nucleons (i.e., protons and neutrons). Over the course of millions of years, these stars progressively cool down, radiating heat into ...

"It is fascinating to concretely see how each new neutron-star observation enables us to deduce the properties of neutron-star matter with increasing precision." When you purchase through links on our ...

A collaboration between quantum physicists and astrophysicists has achieved a significant breakthrough in understanding neutron star glitches. They were able to numerically simulate this enigmatic ...

Neutron stars are what remain after giant stars collapse, leaving behind a body so dense that its core crushes protons and neutrons into a tightly packed soup. These objects cool very slowly over ...

An international team of astrophysicists from China and Australia has for the first time determined how massive neutron stars are when they are born. "Understanding the birth masses of neutron stars ...
