Wd 1856 b
Another recent discovery, WD 1856+534 b (WD 1856 b, for simplicity), is an even stronger candidate for a gi-ant planet orbiting a WD, as it was discovered through the transit method (Vanderburg et al.2020). This planet orbits its WD host on an even shorter orbit than that estimated for WD J0914, at only about 0:02 AU."The satellite spotted WD 1856 b about 80 light-years away in the northern constellation Draco. It orbits a cool, quiet white dwarf that is roughly 11,000 miles (18,000 kilometres) across, maybe up to 10 billion years old, and is a distant member of a triple star system," Nasa's statement further read.

WD 1856 b to have been ∼2.5au, and its mass to be ;0.7–3M J. These mass limits put WD 1856 b firmly within the planet category. Furthermore, our inferred values imply that WD 1856 b was born a typical gas giant. We further estimate the occurrence rate of Kozai-migrated planets around WDs to be ()10 10--34- , suggesting that Dec 7, 2021 · 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.

This system is challenging to observe due to the faintness of the host star and the short transit duration.Gaia DR2 2146576589564898688 b. Description. Whereas some white dwarfs show evidence for rocky material floating in their atmospheres, WD 1856+534 b is the first giant planet candidate transiting a white dwarf. During a star's red giant phase, any close-orbiting planets will be engulfed by the star, but more distant planets can survive this ...Instead, WD 1856 b is thought to have formed at greater separations, and to have migrated inward after the main sequence (MS). Although WD 1856 b is a cool ( <200 K) object, its orbit resembles those of the "hot Jupiters" that accompany ∼1% of MS stars (e.g., Howard et al. 2012).A new planet dubbed WD 1856 b has been found intact even as it orbits a white dwarf, the corpse of a dead star.; Dead stars normally rip apart any planet that dares to come close. Located only 80 ...
On the other hand, WD 1856+534 b seems to be somewhat stable and is quite substantial $(M\sim10\text{-}15M_J$), likely falling into the giant planet regime. It's certainly true that we don't know that the planet formed before the progenitor became a white dwarf, and it definitely can't be ruled out.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.
