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. We here reconstruct the evolutionary history of the system assuming common envelope evolution as the main mechanism that brought the planet to its current position. We find …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).In this artist's illustration, the Jupiter-sized planet WD 1856 b orbits the white dwarf every day and a half.

"WD 1856 b somehow got very close to its white dwarf and managed to stay in one piece," said Andrew Vanderburg, an assistant professor of astronomy at the University of Wisconsin-Madison. "The white dwarf creation process destroys nearby planets, and anything that later gets too close is usually torn apart by the star's immense gravity.

WD 1856 b is located about 80 light years away in the northern constellation Draco. The team behind the paper believes the gaseous planet was pulled in by the white dwarf’s gravity long after the star had dwindled down from its red giant phase — otherwise the planet would have been obliterated in its current orbit.1,856 Free images of Bangkok.
