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

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

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 ...

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.

The black hole becomes a kind of parasite: quietly embedded within the white dwarf, feeding ever so slowly. This allows the white dwarf to survive with a small "endoparasitic" black hole (EBH) at ...

Astronomers have discovered the "missing link" connecting the death of sunlike stars to the birth of white dwarf stellar remnants, in the form of a "teenage vampire" white dwarf.

We call objects like these white dwarfs, and the Sun is destined to become one. This quantum pressure was not a hard limit though. Back in 1931, Subrahmanyan Chandrasekhar calculated that you can ...

The white dwarf would be difficult to shred thanks to being extremely compact, and could have already existed in the accretion disk before moving closer to the black hole, potentially explaining ...

Stars which become black holes are enormous. Slightly smaller than that, and they might make neutron stars. And smaller than that, they make something called a white dwarf.

Curious about the supermassive black hole at the center of our galaxy? Wondering what will happen when the Sun’s core collapses, forming a white dwarf? Explore these fascinating phenomena during this ...

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 ...
