For the first time, researchers have observed an X-ray explosion on a white dwarf
When stars like our sun use up all their fuel, they shrink to form white dwarfs. Sometimes such dead stars flare back to life in a super-hot explosion and produce a fireball of X-ray radiation. A research team from several German institutes including Tübingen University, and led by Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), has now been able to observe such an explosion of X-ray light for the very first time.
