Star Evolution

What different kinds of supernovae occur in the universe?

There are two general types of supernovae. A Type I supernova is the result of an existing, older white dwarf that gains enough mass to exceed the Chandrasekhar limit, causing a runaway collapse. A Type II supernova is produced by a single high-mass star whose gravity is so strong that its own weight causes the stellar core to reach a mass beyond the Chandrasekhar limit.
