1930 – Subrahmanyan Chandrasekhar discovers the white dwarf maximum mass limit. 1933 – Fritz Zwicky and Walter Baade propose the neutron star idea and suggest that supernovae might be created by the collapse of normal stars to neutron stars—they also point out that such events can explain the cosmic ray background.
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 ...
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 ...
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]
The observations made using the European Space Agency's XMM-Newton orbiting X-ray telescope appear to show a white dwarf nearing the point of no return - called the event horizon - as it orbits ...
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 ...
A Type Ia supernova (read: "type one-A") is a type of supernova that occurs in binary systems (two stars orbiting one another) in which one of the stars is a white dwarf. The other star can be anything from a giant star to an even smaller white dwarf. [1] Physically, carbon–oxygen white dwarfs with a low rate of rotation are limited to below ...
What exactly is a white dwarf star, you ask? NASA explains, "As stars like our sun age, they puff up into red giants and then gradually lose about half their mass, shrinking down to 1/100th of ...
