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 ...
Van Maanen 2, or van Maanen's Star, is the closest known solitary white dwarf to the Solar System. It is a dense, compact stellar remnant no longer generating energy and has equivalent to about 68% of the Sun's mass but only 1% of its radius. [ 9 ]
Vesta is a rocky object in our solar system's main asteroid belt with a diameter of about 330 miles (530 km). ... This white dwarf started its life as a star about twice the sun's mass, living a ...
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.
G 240-72 is the seventh closest white dwarf (after Sirius B, Procyon B, van Maanen's star, Gliese 440, 40 Eridani B and Stein 2051 B). Its trigonometric parallax , as measured by the Gaia space telescope, is 160.9952 ± 0.0119 mas , [ 1 ] corresponding to a distance of 6.2114 parsecs (20.259 light-years ).
LP 658-2 is a degenerate (white dwarf) star in the constellation of Orion, [3] the single known object in its system. It has an apparent visual magnitude of approximately 14.488. [ 2 ]
WD 1856+534 is a white dwarf located in the constellation of Draco.At a distance of about 25 parsecs (80 ly) from Earth, it is the outer component of a visual triple star system consisting of an inner pair of red dwarf stars, named G 229-20.
