The weird outbursts of a distant supermassive black hole may be caused by a death-defying white dwarf walking a cosmic tight ...

The density of the white dwarf might give it an advantage, it is not easily disrupted by a black hole weighing about one million times the mass of the Sun. Still, the X-ray observations of the ...

Astronomers have been aware of cosmic vampires, dead stars that hungrily strip plasma from victim stars, for some time. New ...

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.

How white dwarfs mimic black holes Date: December 17, 2012 Source: University of Southampton Summary: Astronomers have revealed that bright X-ray flares in nearby galaxies, once assumed to ...

When a red giant first snuck too close, the black hole snatched away all its hydrogen, leaving just the core white dwarf behind. But the black hole, which contains about 400,000 times the mass of ...

Based on this new data, the team believes that X9 is a binary system containing a black hole that strips mass from a white dwarf as the latter orbits at a distance of just about 2.5 times the ...

A black hole dines on material that approaches too near it, and this food powers the black hole. For this reason, black holes do not “die” in the way that white dwarf stars fade.

The black hole in question is 1ES 1927+654, located around 270 million light-years from Earth, with a mass around 1.4 billion times that of the sun. 1ES 1927+654 first announced its weirdness to ...

Since the white dwarf is losing so much mass, it might eventually end up planet-sized. The mass loss might not stop there: it could ultimately evaporate completely, devoured by its black hole ...
