In the 1930s Fritz Zwicky, Walter Baade, and Rudolph Minkowski developed several models of them. The first type involves a carbon-oxygen white dwarf pulling matter from a companion star until it passes the Chandrasekhar limit. In the second type, heavy elements are produced in a star's core until silicon is produced, which fuses into iron in less than a day. Both types involve catastrophic collapse of the core. FTP identify these dramatic star deaths, the most energetic bangs since the Big one.
