What type of supernova resulted in the formation of Tycho's SNR?

Tycho's Supernova Remnant (SNR) is the result of a Type Ia supernova. A Type Ia supernova occurs in a binary star system where one star is a white dwarf, which has accreted material from a companion star. When the white dwarf's mass approaches the Chandrasekhar limit (approximately 1.4 times the mass of the Sun), it becomes unstable and undergoes a catastrophic explosion. This explosion produces an exceptionally bright event, and the remnants of the explosion, like Tycho's SNR, are visible long after the event.

Type Ia supernovae are particularly important in astrophysics because they provide standardized candles for measuring astronomical distances due to their consistent maximum brightness. Tycho’s SNR, which was observed by the astronomer Tycho Brahe in 1572, is one of the most studied remnants of a Type Ia explosion, allowing scientists to learn more about the nature of white dwarfs and the dynamics of supernova events.

In contrast, Type II supernovae are the result of a core-collapse of massive stars, which do not fit the formation mechanism of Tycho's SNR. Similarly, Type Ib supernovae follow a core-collapse phenomenon but originate from stars that have lost
