For 10 points, name this giant stellar explosion.
Types of these events are differentiated by determining whether their spectra exhibit the Balmer series. Some of these events are candidates for the r-process, which creates heavy elements. Another type of this event is initiated when a white dwarf accretes enough matter to undergo carbon-carbon fusion, yet another occurs when a nickel-iron core starts building up and exceeds the Chandreshekar limit, which leads to core collapse until it is stopped by (*) electron degeneracy pressure. The energy then rebounds, creating this event. These events are differentiated into the Type I and Type II varieties, respectively. For 10 points, name this giant stellar explosion.
