A less common observable evidence is infrared excess due to a flat and optically thick debris disk, which is found in around 1%–4% of white dwarfs. [155] The first white dwarf with infrared excess was discovered by Zuckerman and Becklin in 1987 in the near-infrared around Giclas 29-38 [160] and later confirmed as a debris disk. [161]
First discovered Sirius B: 1852 Sirius system Sirius B is also the nearest white dwarf (as of 2005) [2] [3] First found in a binary star system First double white dwarf system LDS 275: 1944 L 462-56 system [4] First solitary white dwarf Van Maanen 2: 1917 Van Maanen's star is also the nearest solitary white dwarf [5] First white dwarf with a planet
WD J0914+1914 is the first single white dwarf star found to have a giant planet orbiting it. Evidence of the giant planet was discovered by a team of astronomers from the UK, Chile and Germany.
1910 – the spectrum of 40 Eridani B is observed, making it the first confirmed white dwarf. 1914 – Walter Sydney Adams determines an incredibly high density for Sirius B. 1926 – Ralph Fowler uses Fermi–Dirac statistics to explain white dwarf stars. 1930 – Subrahmanyan Chandrasekhar discovers the white dwarf maximum mass limit.
A new type of stellar object has been discovered releasing energetic bursts of radio waves every 22 minutes. ... either a dense neutron star or a dead white dwarf star — with a strong magnetic ...
The planet is in a circumbinary orbit around the two stars of PSR B1620-26 (which are a pulsar (PSR B1620-26 A) and a white dwarf (WD B1620-26)) and is the first circumbinary planet ever confirmed. It is also the first planet found in a globular cluster.
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 ...
