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 ...
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. [121] A second white dwarf pulsar was discovered in 2023. [122]
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 ...
Astronomers have discovered a white dwarf star, or the burnt core of a dead star, that has two completely different faces. One is made of hydrogen, while the other is made of helium.

The Hertzsprung–Russell diagram showing the location of main sequence dwarf stars and white dwarfs. A dwarf star is a star of relatively small size and low luminosity. Most main sequence stars are dwarf stars. The meaning of the word "dwarf" was later extended to some star-sized objects that are not stars, and compact stellar remnants that ...
As white dwarf stars form at the end of a star's main sequence evolutionary period, such a long-lived star system may have wandered far from the region where it originally formed. Thereafter a close binary system may spend another million years in the mass transfer stage (possibly forming persistent nova outbursts) before the conditions are ...
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 ...
