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

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 ...

White dwarfs are the dense cores left behind when stars burn through their fuel. Researchers say most have thick outer layers ...

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

The white dwarf is depicted above the Moon in this artistic representation; in reality, the white dwarf lies 130 light-years away in the constellation of Aquila.

More 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. This vampire ...

Zombie white dwarf stars keep their heavy metal exteriors fresh by constantly cannibalizing any smaller objects in their dead planetary systems, like comets and asteroids, that get in their way.

Some white dwarfs, including AE Aquarii, spin very rapidly and have magnetic fields millions of times stronger than Earthu001as. These characteristics give them the energy to generate cosmic rays.

Whereas white dwarfs have incredibly high densities by earthly standards, neutron stars are even denser, cramming roughly 1.3 solar masses into a city-sized sphere.
