University of Warwick astronomers have uncovered compelling evidence that a nearby white dwarf is in fact the remnant of two ...

An international team of astronomers using the Hubble telescope has discovered an ultra-massive white dwarf formed not from a ...

A typical white dwarf’s core elements are obscured by thick layers of hydrogen and helium—but that covering almost entirely ...

A rare white dwarf merger remnant emerges in ultraviolet light, revealing thin layers of hydrogen and helium stripped away ...

Astronomers discover a rare white dwarf formed by a stellar merger, challenging what we know about star death and cosmic collisions.

When the two white dwarfs merged, they combined to form a new star, about 1.35 times the mass of our sun, the most massive of its kind ever found.

Astronomers have discovered a white dwarf star, or the burnt core of a dead star, that has two completely different faces. One is made of hydrogen, while the other is made of helium.

The fountain of stellar youth White dwarfs are born when stars that possess around the same mass as the sun exhaust the fuel supply necessary for nuclear fusion at their cores. This supply is made ...

A second white dwarf, Sirius B (orbiting the star Sirius), was discovered soon after and appeared incredibly dense (about 200,000 times as dense as Earth).

While it's reasonably certain that white dwarfs—the Earth-size remnant of stars similar to the Sun—are involved, the observational evidence for how these supernovae actually explode is messy.
