(Phys.org)—Neutron stars, which form when massive stars collapse under their own enormous gravity, are some of the densest objects in the universe, second only to black holes. Yet while little is known about the interiors ...
(PhysOrg.com) -- An international team of physicists studying the Crab Nebula have offered a new theory to explain its extraordinarily high energy emissions that have intrigued space scientists for years. The team, led by ...
How large is a neutron star? Previous estimates varied from eight to 16 kilometres. Astrophysicists at the Goethe University Frankfurt and the FIAS have now succeeded in determining the size of neutron stars to within 1.5 ...
