The matter inside a neutron star consists mostly of neutrons, with a few protons, electrons, and other sub-atomic particles. This matter is so dense that an entire neutron star, with a mass greater ...

A neutron star is what remains after a massive star goes supernova. Composed entirely of neutrons, this compact star possesses a radius of only a dozen kilometers (approx. 7 miles) but has a mass that ...

A team of researchers from the Massachusetts Institute of Technology used Frontier to chart the isospin density of a neutron star over a range of conditions. This illustration depicts isospin-dense ...

Neutron stars are some of the weirdest cosmic objects, and the greatest mysteries lie deep in their hearts.

New insights into the properties of neutron stars have come from two independent analyses of gravitational waves from the GW170817 neutron-star merger. The work was done by teams led by Farrukh ...

Astrophysicists modeling the insides of neutron stars have found that the extremely compact objects have different internal structures, depending on their mass. They suggest thinking of the stars as ...

Inside a neutron star—the city-size, hyperdense cinder left after a supernova—modern physics plunges off the edge of the map. There, gravity squeezes matter to densities several times greater than ...

A mystery lurks inside the corpses of dead stars. Neutron stars, formed when certain types of stars die in supernova explosions, are the densest form of matter in the universe; black holes are the ...
