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. [156] The first white dwarf with infrared excess was discovered by Zuckerman and Becklin in 1987 in the near-infrared around Giclas 29-38 [161] and later confirmed as a debris disk. [162]
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.
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 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 ...
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 ...
First known planet orbiting a white dwarf. PSR B1620-26 b: PSR B1620-26: 1993 Orbits a pulsar and a white dwarf. Discovery confirmed in 2003. GD 66 b was announced in 2007, but has not been confirmed. First known extrasolar planet orbiting a main sequence star (Sun-like) 51 Pegasi b: 51 Pegasi: 1995 First hot Jupiter. [41] First known planet ...
"White dwarfs form at the very end of a star's life. About 97% of all stars are destined to become white dwarfs when they die," Caiazzo said. "Our sun, for example, is currently burning hydrogen ...
The supposed planetesimal, WD 1145+017 b, [13] with a 4.5 hour orbit, is being ripped apart by the star and is a remnant of the former planetary system that the star hosted before becoming a white dwarf. [8] [9] It is the first observation of a planetary object being shredded by a white dwarf. Several other large pieces have been seen in orbit ...
