Two teams of astronomers have simultaneously discovered a strange, spinning dead star that seems to defy our current understanding of both neutron stars and white dwarfs.

Both teams releasing papers detected the object independently, using different sets of data. Both teams found the same ...

"So, even knowing the mass exactly does not answer the question of if this hidden companion is a white dwarf or a neutron star." The team was able to find some clues that indicate that the dead ...

A strange star deep in space has been left with a metallic scar across its surface after eating one of its own planets. The star—named WD 0816-310—is a white dwarf star situated around 63 ...

A white dwarf and a red dwarf star have been discovered closely orbiting each other emitting radio pulses every two hours. Their findings means we know it isn't just neutron stars that emit such ...

At first, the team thought that ASKAP J1839-0756 might be a white dwarf, a smaller star like our sun that has died. “But we've never seen an isolated white dwarf emitting radio pulses and our ...

The explosion of a star, called a supernova, is an immensely violent event. It usually involves a star more than eight times the mass of our sun that exhausts its nuclear fuel and undergoes a core ...

This accreted matter piles up on the surface of the stellar remnant, increasing the mass of the white dwarf beyond the so-called Chandrasekhar limit, which is equal to 1.4 times the mass of the sun.

An international team of astronomers reports the discovery of a new long-period radio transient, which received the ...

A white dwarf and a red dwarf star have been discovered closely orbiting each other emitting radio pulses every two hours. Their findings means we know it isn't just neutron stars that emit such ...

Incredibly rapid gas flares from a white dwarf binary star system have been detected for the first time by Oxford University scientists. The first sighting of such activity, it suggests that our ...
