What is the defining difference in mechanism between a Type Ia supernova and a Type II supernova?
Answer
Type Ia involves the complete detonation of a white dwarf, while Type II results from core collapse of a massive star
Type Ia supernovae occur when a white dwarf accumulates too much mass and detonates entirely, leaving no remnant. Type II supernovae occur when a massive star exhausts its fuel, causing its core to collapse.
