Artist impression of an exploding white dwarf. Credit: University of Tübingen When stars like our Sun run out of fuel, they contract to form white…
This illustration is an artist’s impression of the thin, rocky debris disc discovered around the two Hyades white dwarfs. Rocky asteroids are thought to have…
The fast shockwaves form an hourglass shape as they expand, in which gamma rays are produced. This gamma-ray emission is then detected by the H.E.S.S.…
Artist’s impression of a white dwarf, G29—38, accreting planetary material from a circumstellar debris disk. When the planetary material hits the white dwarf surface, a…

A Smoldering Stellar Corpse on the Edge: Astronomers Spot a White Dwarf So Massive It Might Collapse
This illustration highlights a newfound small white dwarf, discovered by ZTF, that is 4,300 kilometers across, or roughly the size of Earth’s moon, which is…
Illustration of the origin of magnetic fields in white dwarfs in close binaries (to be read counter clockwise). The magnetic field appears when a crystallizing…
Remnants of planetary crust disintegrating under the tidal forces around a cool white dwarf. Material in the disc becomes vapourised close to the central star…
Artist’s interpretation of the explosion of a recurrent nova, RS Ophiuchi. This is a binary star in the constellation of Ophiuchus and is approximately 5,000…
WD 1856 b, a potential planet the size of Jupiter, orbits its dim white dwarf star every 36 hours and is about seven times larger.…
For just the second time ever, astrophysicists have spotted a spectacular flash of ultraviolet (UV) light accompanying a white dwarf explosion. An extremely rare type…

Illustration of a white dwarf, the dead remnant of a star like our Sun, with a crystallised, solid core. White dwarfs are the remains of…
Astronomers have detected a bright X-ray outburst from a star in the Small Magellanic Cloud, a nearby galaxy almost 200,000 light years from Earth. A…
