WebIf a white dwarf is in a binary star system and is accreting matter from its companion, a variety of phenomena may occur, including novae and Type Ia supernovae. It may also be a super-soft x-ray source if it is able to take material from its companion fast enough to sustain fusion on its surface.

The more massive star evolves first to become a red giant and then a white dwarf. The white dwarf then begins to attract material from its companion, which in turn evolves to become a red giant. Eventually, the white dwarf acquires so much mass that it is pushed over the Chandrasekhar limit and becomes ...
The habitability of red dwarf systems is presumed to be determined by a large number of factors from a variety of sources. Modern evidence indicates that planets in red dwarf systems are unlikely to be habitable, due to their low stellar flux, high probability of tidal locking, small circumstellar habitable zones and the high stellar variation experienced by planets of red dwarf stars, impeding their pla… WebOct 7, 2024 · An explosive cannibal white dwarf has been discovered in an incredibly close orbit around its stellar victim, proving a 30-year-old theory about how such binary star systems evolve.
