(Vanderburg et al. 2020) Oct 20, 2020 · A NASA satellite known as TESS may have discovered a massive extrasolar planet twice as old as any planet in our solar system. While astronomers need to conduct more observations to confirm the planet exists, this gas giant world, named WD 1856 b and located 80 light years away in the constellation Draco, appears to be 14 times more massive than Jupiter, and around 10 billion years old. “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.Very recently, Vanderburg et al. reported the discovery of a giant planet candidate, WD 1856 b, orbiting the cool and old white dwarf WD 1856+534 (hereafter WD 1856) with a short orbital period (≃1.4 d).Last year, a team found an intact Jupiter-like planet called WD 1856 b orbiting a white dwarf, reports Becky Ferreira for the New York Times.

We used the GTC telescope to obtain and analyse photometry and low resolution spectroscopy of six transits of WD 1856+534 b, with the intention to derive the slope of the transmission spectrum, towards an eventual detection of Rayleigh scattering of the particles in ... 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 that common envelope evolution can explain ...The planet, named WD 1856 b, is roughly the size of Jupiter, making it about seven times bigger than the star it’s orbiting, named WD 1856+534.

Given the difficulty in forming WD 1856 b ... 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 thatWD 1856 b is located about 80 light years away in the northern constellation Draco, the researchers said. They believe the gaseous planet was pulled in by the white dwarf's gravity long after the ...Washington: Scientists have, for the first time, discovered a Jupiter-sized planet orbiting a white dwarf or a dead star located about 80 light years away.

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 ...WD 1856 b is located about 80 light years away in the northern constellation Draco, the researchers said. They believe the gaseous planet was pulled in by the white dwarf's gravity long after the ...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.“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.Hence, the detection of WD 1856 b with a ‘grazing’ transit suggests there could be ∼10 times as many systems where the WD is completely blocked. However, no other transit of a WD by a giant planet has been detected by TESS thus far, suggesting that the transit geometry of WD 1856 b is ‘lucky’ (Vanderburg, private communication).Unlikely to have endured stellar evolution in its current orbit, WD 1856 b is thought to have migrated from much wider separations.
