The statistical distribution of the total mass of 14 double neutron star (DNS) systems (out of 18 pairs observed) is found to be very narrow, with the average and standard deviation as 2.65 ± 0.03 M☉.

Paul D. Lasky is in the School of Physics and Astronomy, Monash University, Melbourne 3800, Australia. Nuclear physicists cannot calculate how matter should behave during and immediately after these ...

The cosmos has delivered a rare kind of fireworks display, and astronomers are racing to understand what it means. A strange double flash from a distant galaxy appears to show two neutron stars ...

When a massive star dies in a supernova, the explosion is only the beginning of the end. Most of the stellar matter is thrown far and wide, but the star’s iron-filled heart remains behind. This core ...

A surprisingly bright cosmic blast might have marked the birth of a magnetar. If so, it would be the first time that astronomers have witnessed the formation of this kind of rapidly spinning, ...

Neutron stars are covered with "mountains" only fractions of a millimeter tall, new research shows, meaning these bumps are hundreds of times smaller than previous estimates had suggested. Now, new ...

Researchers used advanced computers and real observations to see the 3D shape of light emanating from a merger between ultradense stellar bodies. When you purchase through links on our site, we may ...
