Astronomers have captured the first-ever visual evidence of a white dwarf star exploding twice in a remarkable supernova event. The discovery, made by studying the remnants of supernova SNR 0509 ...

WASHINGTON (Reuters) -Astronomers have spotted two hefty white dwarf stars - highly compact stellar embers - orbiting close together that appear destined to die in an extraordinarily violent ...

About 8,150 light-years from Earth, a white dwarf star named Gaia22ayj has intrigued astronomers. Its unusual behavior, characterized by extreme pulsations, has led to a major discovery about the life ...

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 ...

This white dwarf belongs to an extremely rare class of objects called long-period transients (LPTs). Only ten of these slow-pulsing radio sources have been discovered so far, making each new find ...

That's because Gaia22ayj is actually a white dwarf feeding on a companion star, with this binary in a rare and short-lived phase of its life (or should that be death).

Finding dark dwarfs would go a long way to answering the question about the nature of dark matter. If we could detect some dark dwarfs, it would bolster the idea that dark matter is WIMPs.

White dwarfs, as the compact remnants of low- to intermediate-mass stars, serve as the engines of these cataclysmic variables. Their high densities and strong gravitational fields facilitate the ...
