Evolution of Brightness for Two Quick Transient Events and Two Typical Supernovae

Caption

Graph showing the evolution of brightness for two quick transient events and two typical supernovae: thermonuclear and core-collapse. In thermonuclear supernovae an Earth-sized remnant (a white dwarf) of a small sun-like star accretes a critical mass of material from a companion star and explodes. In a core-collapse supernova a massive star exhausts the fuel in its core which causes the core to collapse, triggering an explosion.
