character: Type I Supernova
topic: Type I supernovae are caused by the explosion of a white dwarf star that accumulates too much mass from a companion star, leading to a runaway nuclear reaction.
topic: Type I supernovae are characterized by their lack of hydrogen lines in their spectra, a consistent peak brightness which makes them useful as standard candles for measuring astronomical distances.
topic: The main cause of Type I supernovae is the white dwarf star reaching the Chandrasekhar limit, about 1.4 times the mass of the Sun, which triggers a rapid increase in temperature and pressure causing explosive nuclear fusion.
topic: Unlike Type I supernovae, Type II supernovae occur in massive stars that have exhausted their nuclear fuel, leading to a core collapse and subsequent explosion, often resulting in the formation of a neutron star or black hole.
