This is a list of exceptional white dwarf stars.

Firsts

[edit]

These were the first white dwarfs discovered fitting these conditions

Title Star Date Data Comments Notes Refs
First discovered Sirius B 1852 Sirius system Sirius B is also the nearest white dwarf (as of 2005) [1][2]
First found in a binary star system
First double white dwarf system LDS 275 1944 L 462-56 system [3]
First solitary white dwarf Van Maanen 2 1917 Van Maanen's star is also the nearest solitary white dwarf [4]
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 [5][6]
First singular white dwarf with a planet WD 1145+017 2015 WD 1145+017 b Planet is extremely small and is disintegrating.
First white dwarf that is a pulsar AR Scorpii A 2016 The star is in a binary system with a red dwarf [7]

Extremes
