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 planetesimal, most likely an asteroid. [8] First white dwarf that is ...
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. [120] A second white dwarf pulsar was discovered in 2023. [121]
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.
The ancient Roman god Janus was two-faced, literally - with one looking forward and another backward, representing transitions and duality. Scientists have observed a white dwarf star - a hot ...
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 ...
An exoplanet orbits PSR B1620-26 and its white dwarf companion (see below) in a circumbinary orbit. HD 49798: 1,600 White dwarf: One of the smallest white dwarf stars known. [14] ZTF J1901+1458: 1,809 Currently the most massive white dwarf known. [15] Janus: 3,400 A white dwarf with a side of hydrogen and another side of helium. [16] Wolf 1130 ...

Like other white dwarfs, it is a very dense star: its mass has been estimated to be about 67% of the Sun's, [28] yet it has only 1% of the Sun's radius (1.23 times the Earth's radius) [8] [a] The outer atmosphere has a temperature of approximately 6,110 K, [28] which is relatively cool for a white dwarf. As all white dwarfs steadily radiate ...
