Debris ring and planet around white dwarf, illustration
Bildnummer 12660017
| Artist's impression of a disintegrating exoplanet orbiting within a planetary debris disc. This planet was found by a team led by Warwick University and announced in 2019. They were looking at a dusty ring around the central star, a white dwarf, when the latter underwent a supernova explosion. A signal in their data, repeating every two hours, indicates the presence of a moving stream of gas in the ring, orbiting the white dwarf rapidly. The object emitting the gas stream is estimated to be an 800-km-wide asteroid-like body, similar in size to Ceres, but made almost entirely of iron. | |
