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☉.

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 ...

What does a lead nucleus and a neutron star have in common? When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Scientists have made new estimates of ...

Neutron stars are ultra-dense star remnants made up primarily of nucleons (i.e., protons and neutrons). Over the course of millions of years, these stars progressively cool down, radiating heat into ...

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 ...

Neutron stars are incredibly dense, city-sized remnants of massive stars. They form after a supernova when gravity overcomes electron degeneracy pressure. Some neutron stars, called pulsars, emit ...

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, ...

The heaviest neutron star ever detected is shredding its companion while spinning on its axis over 700 times per second. The neutron star, known as PSR J0952-0607, was discovered in 2017 about 3,000 ...

Astronomers are on the hunt for the remnants of the neutron-star collision that gave Earth its precious metals. When neutron stars merge, they spew a wealth of short-lived elements into their ...
