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

Now, through computer modeling and observational analysis, researchers have recreated the structure of the remnant white dwarf, a rare occurrence, explaining its double shock formation.

The team that made the discovery was led by the University of Cambridge and used data from two telescopes to measure how the light of a distant star bent around the white dwarf star known as LAWD 37.

In 1181 AD, during the Genpei War, a mysterious star appeared in Asia’s skies for a brief time before disappearing again. For 843 years, the cosmic event was a source of confusion for astronomers.

In a remarkable celestial find, astronomers have made an intriguing discovery in our cosmic vicinity—a white dwarf star that is undergoing a fascinating transformation into a massive diamond ...

The white dwarf, or dead star, in question is the compact companion of the star HD 49798, which is located around 1,700 light-years away from Earth with a mass around 1.5 times that of the sun.

Astronomers have discovered a "teenage vampire" dead star in the process of devouring a companion star during a short-lived, "missing link" phase of its evolution.

Even among the ultra-hot white dwarfs known by the designation PG1159, the selection that cropped up in this survey lack the helium normally found in their atmosphere: instead, they’ve burned it ...

It is a white dwarf star that was once "several times more massive" than the Earth's sun. It has been in the process of dying for over 4,000 years, and "will continue to change over many more ...

Astronomers have discovered a pair of white dwarf stars locked in a tight orbital dance, hurtling towards a spectacular and violent end.. Located a mere 160 light-years from Earth within our Milky ...
