Like all neutron stars, pulsars have quite tightly constrained masses and sizes, most neutron stars have a mass of around 1.5 times that of the sun. One respect in which pulsars vary a lot is ...

known as millisecond pulsars, can have frequencies above 700 Hz. It's pretty astonishing when you think about it. An object with nearly twice the mass of the sun, but only a few kilometers across ...

Pulsars are the rapidly spinning remains of dying stars—the leftover cores of supernova explosions. They're only about 12 to 15 miles in diameter, but most contain more than twice the mass of ...

Astronomers may have discovered a rare type of binary star system, where one star used to orbit inside its partner.

Despite their small diameters—about 12.5 miles (20 kilometers)—neutron stars boast nearly 1.5 times the mass of our sun ... some neutron stars the name pulsars. After spinning for several ...

Astronomers may have identified a rare binary star system where one star orbits within the volume of its companion. This ...

Pulsars are formed from the remnants of massive stars that have ended their life cycles in supernova explosions. When a star with a mass between about 10 and 25 times that of the sun exhausts its ...

The stars in a binary can vary widely in mass, size, and brightness, and their interactions often shape their evolution in ...

These pulsars – short for ‘pulsating stars’ – are dense objects, with a mass roughly the same as that of our Sun, but a radius that is around 100,000 times smaller, only about 10 km.
