Indian astronomers have performed X-ray observations of an X-ray binary designated 4U 1907+09. Results of the observational ...

A neutron star's almost incomprehensible density causes ... As they compress and shrink, this spinning speeds up because of the conservation of angular momentum—the same principle that causes ...

New research led by W. M. Keck Observatory Instrument Scientist and astronomer Grant Hill has confirmed what scientists have long suspected—WR 104 comprises two massive stars: a Wolf-Rayet star and an ...

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.

"This work provides a crucial foundation for interpreting gravitational wave detections of neutron star mergers." Neutron stars are the dense remnants of massive stars, more than eight times as ...
