Wd 1856 b
The Jovian-sized object WD 1856 b transits a white dwarf (WD) in a compact 1.4 day orbit. Unlikely to have endured stellar evolution in its current orbit, WD 1856 b is thought to have migrated from much wider separations. Because the WD is old, and a member of a well-characterized hierarchical multiple, the well-known Kozai mechanism provides an effective migration channel for WD 1856 b. The ... In the case of WD 1856+534, we’re dealing with a white dwarf that formed almost 6 billion years ago, following the star’s red giant phase, long enough to allow a rocky planet in a circularized orbit to spawn its own version of life. The original star is thought to have formed about 10 billion years ago. Ah, okay.In this artist's illustration, the Jupiter-sized planet WD 1856 b orbits the white dwarf every day and a half. NASA's Goddard Space Flight Ce This illustration shows a carbon-rich planet with ...

The discovery of a giant planet candidate orbiting the white dwarf WD 1856+534 with an orbital period of 1.4 d poses the questions of how the planet reached its current position.WD 1856+534 b is a Jupiter-sized, cool giant planet candidate transiting the white dwarf WD 1856+534. Here, we report an optical transmission spectrum of WD 1856+534 b obtained from ten transits using the Gemini Multi-Object Spectrograph. This system is challenging to observe due to the faintness of the host star and the short transit duration.
