Simulations of highly magnetized stars that explode and collapse into black holes show that they transfer their magnetic fields to the disk of swirling matter that forms around the new black hole.

Indian astronomers have observed an X-ray binary system designated SXP 138. Results of the NuSTAR observations, published ...

Approximately 980 million light-years away from Earth, in the center of the galaxy SDSS1335+0728 in the constellation Virgo, ...

and they form either a neutron star or a black hole in the center. And then the material that was trying to explode out instead gets swallowed in by the black hole, forms an accretion disk ...

However, in these systems, the first-born neutron star typically gains extra mass from its companion, through a process called accretion, making it difficult to determine its original birth mass.

X-Ray Pulsars are magnetized Neutron Stars. In Binary systems, when the Neutron Star enters the accretion regime, it starts to accrete matter from its optical counterpart which acts as the donor here.

Neutron stars are very small and dense stars, where roughly half a million earth masses of material are squeezed into a city-sized volume with a radius of 10 km. They are mostly composed of ...
