The highly magnetized white dwarf in the binary system AR Scorpii was identified in 2016 as the first pulsar in which the compact object is a white dwarf instead of a neutron star. [118] A second white dwarf pulsar was discovered in 2023. [119]
Van Maanen's star is also the nearest solitary white dwarf [5] First white dwarf with a planet WD B1620−26: 2003 PSR B1620-26 b (planet) This planet is a circumbinary planet, which circles both stars in the PSR B1620-26 system [6] [7] First singular white dwarf with a transiting object WD 1145+017: 2015 Known object is a disintegrating ...
Scientists have detected emanating from the nucleus of a galaxy relatively close to our Milky Way flashes of X-rays gradually increasing in frequency that seem to be coming from a white dwarf - a ...
The central star, a white dwarf progenitor, is estimated to have a radius which is 0.055 ± 0.02 R ☉ (0.13 light seconds) which gives it a size larger than most other known white dwarfs. [6] Its mass was estimated in 1999 by Napiwotzki to be 0.56 ± 0.01 M ☉. [6]
This dead, dense star remnant is called a white dwarf." As this is the first time scientists have ever seen this "catastrophic destruction" in action, it's a pretty monumental moment for astronomers!
A slowly cooling stellar ember called a white dwarf with a scar on its face is providing new insight into the behavior of certain "cannibal" stars at the end of their life cycle. Using the ...
BPM 37093 (V886 Centauri) is a variable white dwarf star of the DAV, or ZZ Ceti, type, with a hydrogen atmosphere and an unusually high mass of approximately 1.1 times the Sun's. It is 48 light-years (15 parsecs) from Earth in the constellation Centaurus and vibrates; these pulsations cause its luminosity to vary.
White dwarfs are the slowly cooling stars that have cast off their outer layers during the last stages of their lives. Hubble discovers hydrogen-burning white dwarfs enjoying slow ageing Skip to ...
