A new study by Manuel Barrientos and colleagues from the University of Oklahoma reveals that between 0.6% and 2.5% of white dwarfs in our solar neighborhood undergo dramatic cooling delays that could ...

These ancient stars are incredibly dense. A teaspoonful of their matter would weigh as much on Earth as an elephant—5.5 tons.

But in reality, it may be the beginning of a new phase of life for all the objects living in the solar system. When stars like the Sun die, they go through a phase of rapid expansion called the Red ...

How White Dwarfs Get Their KicksNASA’s Hubble Space Telescope is providing strong evidence that white dwarfs, the burned-out relics of stars, are given a “kick” when they form. The sharp ...

White dwarfs, the compact remnants of low- to intermediate-mass stars, offer a unique window into the fate of planetary systems. Recent observational and theoretical work has revealed that many ...

Detonating White Dwarfs As SupernovaeNew model explains how inspiraling dead stars can explode at a rate high enough to match the number of Type Ia supernovae seen in universe A new mathematical ...

Astronomers just took a big step toward a better understanding of white dwarfs, a discovery that could shed light on mysterious dark matter.

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