4. Auroras from neutron stars are created on planets, including Draugr.
PSR 1257+12 was first discovered in 1992. It is a pulsar that is located 2,300 lightyears away from the sun. The pulsar contains a planetary system with three known extrasolar planets. The planet Draugr gets its name from a monstrous undead creature from mythology. It is one of three small, rocky planets. When a massive star explodes, its core forms a neutron star, an Earth-sized object with ridiculously high density. However, scientists don’t expect planets around giant stars to sustain stellar explosions. Nor do they expect them to keep orbiting the newly formed neutron stars. However, three worlds are doing just that around the neutron star, PSR B1257+12.
The neutron stars emit a lot of harmful radiation, including x-rays and gamma rays severely damaging to life on Earth. The three planets going around the neutron star, Ergo, are consistently bathed in radiation. The planets are considered to be as lifeless as planets can be. Planets that are around neutron stars might be a pretty sight from a distance. The neutron star’s radiation can create dazzling auroras on the worlds, similar to Earth and Jupiter. The discovery of planets around a pulsar was unexpected, considering that a pulsar could host planetary companions.
