WebJul 23, 2024 · White dwarfs already play an enormous role in physicists’ current understanding of dark energy as well. Physicists predict that white dwarfs all have the same brightness when they explode. So type Ia supernovae are considered “standard candles,” allowing astronomers to calculate exactly how far the explosions lie from Earth.
WebNov 23, 2024 · Can a white dwarf ever explode? 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 led by FAU has now been able to observe such an explosion of X-ray light for the very first time. WebIn systems where the white dwarf doesn't have an appreciable magnetic field, the infalling gas forms a disc -- an accretion disc -- with the white dwarf at its centre. The gas in the disc spirals down towards the white dwarf, radiating its gravitational potential energy away as it …
