Astronomers found that a 3-billion-year-old white dwarf, LSPM J0207+3331, is still feasting on the metal-rich remains of a shattered world. (CREDIT: NASA’s Goddard Space Flight Center/Scott Wiessinger ...

A burst of X-rays from 8 billion years ago may be the first clear evidence of a white dwarf torn apart by a black hole. The study, coordinated by Dongyue Li and Wenda Zhang of the Chinese Academy of ...

The discovery of a rare type of white dwarf star system provides new understanding into stellar evolution. White dwarfs are small, dense stars typically the size of a planet. They are formed when a ...

A newly detected X-ray transient may reveal the first direct evidence of an intermediate-mass black hole consuming a white dwarf. A newly observed cosmic outburst is giving astronomers a rare glimpse ...

New 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 model created by astrophysicists at the ...

Astronomers used a 3D global computer model to compare the climates of exoplanets in different stellar and orbital configurations. They found that a planet orbiting a white dwarf star would offer a ...

A nearby white dwarf is generating three times more energy than expected, hinting at unknown magnetic processes.

For the first time, researchers have found a way to describe conditions deep in the convection zone of “white dwarf” stars, which are home to some of the densest collections of matter in the Universe.
