White Dwarf G29-38 Accreting Debris
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 plasma is
formed and cools via detectable X-ray emission....

White Dwarfs Accreting Debris
Astronomers from the University of Warwick, UK, have observed a pair of old white dwarf stars, both of which have had their
atmospheres polluted by infalling planetary material. The two stars do not orbit each
others and are not related. One is a coo...

Supernova Progenitor HD265435
... variations from the system (called HD265435) indicate that the larger star is
distorted into a teardrop shape by its dense, white
dwarf companion. Eventually, as more and more material is pulled from the
giant star towards the white dwarf, the latte ...

WD1054-226
The white dwarf WD1054-226 exhibits a constant
stream of transits by debris and or dust in orbit about it, with an underlying period
of 25.02 hours. Astronomers believe that the material orbits within the star's
habitable zone, where the temperature ...

ZTF J0923+4236
The white dwarf shown in the illustration is one of
several that an international team of astronomers has been studying. Called ZTF
J0923+4236, the star exhibits a series of dips in its brightness. The team, led by
Amornrat Aungwerojwit from Naresuan...
