At more than 50 Earth masses, WD 1856+534 b is a gas giant, a planet whose mass is mostly made up of hydrogen and helium, like Jupiter and Saturn. 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.WD 1856 b is thought to have formed at greater sep-arations, and to have migrated inward after the main sequence (MS). Although WD 1856 b is a cool (< 200K) object, its orbit resembles those of the ‘hot Jupiters’ that ac-company ˘1% of MS stars (e.g..Howard et …

Oct 13, 2020 · 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 The object, called WD 1856 b, is roughly the same size as Jupiter, with possibly up to 14 times its mass. About every day and a half, it orbits a white dwarf, a star containing half the Sun’s mass in a space only slightly larger than Earth. TESS hunts for regular dips in starlight caused when planets pass in front of, or transit, their stars.
Oct 19, 2020 · 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.
