This is a list of exceptional white dwarf stars.
Firsts
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 | ||||||
First white dwarf in a planetary system | ||||||
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 | [4][5] | |
First singular white dwarf with a planet | WD 1145+017 | 2015 | WD 1145+017 b | Planet is extremely small and is disintegrating. | ||
