Scientists have observed a new type of black hole that is too heavy to have been born from a star but still too slim to … The ...

Astronomers capture first image of a white dwarf exploding twice in space Rare double-detonation seen in supernova remnant ...

For years, scientists have suspected that stars can meet their doom by a one-two punch of back-to-back explosions — but ...

The explosion of a star, called a supernova, is an immensely violent event. It usually involves a star more than eight times ...

A team of scientists is proposing a bold alternative to the Big Bang theory, suggesting that our universe may have instead ...

The most massive stars, about eight to 12 times heftier than the sun, can explode as supernovae, leading to the most extreme objects in the universe—neutron stars and black holes.

This allows the white dwarf to survive with a small "endoparasitic" black hole (EBH) at its center. From the outside, the star may seem normal—but deep inside, a silent transformation is underway.

Of three possible explanations, one is a white dwarf star caught in the black hole’s gravity. Scientists will monitor the phenomenon to find out for sure, and 2035’s LISA antenna will verify.

White dwarfs are among the most compact objects in the cosmos, though not as dense as a black hole. Stars with up to eight times the mass of our sun appear destined to end up as a white dwarf.

If the hypothetical object orbiting the black hole were a white dwarf, the undead star would be in some sort of tidal limbo, where it would be “starting to get ripped apart a little bit,” she ...

According to the research, the strange behavior of 1ES is caused by a 'white dwarf' that came very close to the black hole. A white dwarf is the remains of a dead star and is made up of matter ...
