NASAtells the storyof a neutron star merger as it unfolds, giving way to a tremendous kilonova explosion. The sun will never become a neutron star, instead ending its life as a white dwarf. But while these stellar remnants are quite as extreme as neutron stars they are still fascinating acc...
The phenomenon was discovered thanks to NASA's Neutron Star Interior Composition Explorer (NICER), mounted on the International Space Station, which recorded 15 explosions between 2017 and 2022. The researchers discovered 15 thermonuclear X-ray bursts from the X-ray binary star system 4U 1820-30 d...

The significant detection or exclusion of a gamma-ray eclipse provides a constraint on the binary inclination angle that depends on the angular size of the companion star as seen from the pulsar. The angular size of the companion star’s Roche lobe only depends on the binary mass ratio,q, a...
the rates are suppressed by a factor of exp(−Δj/kT) where Δjis the BCS gap for either protons or neutrons (j=p, n, respectively). Since this gap energy depends on the density, it alters the predicted rates of cooling in a way that can probe the interior structure of the star....

(Image credit: NASA/DOE/Fermi LAT Collaboration/AEI) Astronomers have discovered an ultra-dense star that orbits with a dying stellar companion once every 93 minutes, making it the fastest-orbiting star of its kind. The speedy object, a kind of neutron star called a millisecond pulsar, rocke...
