"For years a local and massive double white dwarf binary has been anticipated, so when I first spotted this system with a very high total mass on our Galactic doorstep, I was immediately excited ...

Astronomers have found a remarkable pair of stars that may finally prove a long-debated theory. Described in the journal ...

The "new stars" are best seen from the Southern Hemisphere, but people have spotted them from the United States by looking ...

White dwarf stars represent the evolutionary endpoints of medium- and low-mass stars, comprising the dense, electron-degenerate cores left after nuclear fuel exhaustion. In binary systems ...

A cataclysmic variable star isn’t technically a single object. Instead, it’s a compact binary system composed of a white ...

Astronomers from the University of Turku in Finland and elsewhere have performed a broadband spectral and timing study of an ...

Astronomers have, for the first time, witnessed a star meeting a dramatic end by exploding twice. In a study published in ...

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

The researchers used data from four ground-based telescopes to study this binary system. One of the white dwarfs has a mass about 83 per cent that of our sun and the other about 72 per cent.

Gaia22ayj is a binary star system in which a white dwarf star is so close to its companion star that mass is transferred from the companion to the white dwarf. Here, ...

It almost goes without saying that’s enough power to destroy everything within the binary star system. But there will be a long, slow, leisurely stellar dance before that detonation. The two white ...

A rare binary white dwarf system just 150 light-years away will explode in a supernova, solving a long-standing astrophysics puzzle. (CREDIT: Nature Astronomy) ...
