Theoretical and observation evidence concerning the final evolution of stars is reviewed, emphasizing the determination of the masses or mass ranges responsible for various phenomena. Theoretical calculations of single-star evolution up to carbon ignition are examined, and observational evidence obtained from studies of white dwarfs, pulsars, supernova remnants, optical supernovae, and compact binary systems is summarized. It is concluded that: (1) the cutoff mass for stellar explosions is probably around 5 solar masses; (2) the possibility cannot be ruled out that the mass above which stars produce, e.g., optical supernovae might be significantly greater than the mass below which stars evolve into white dwarfs; (3) stars with masses greater than about 15 to 20 solar masses probably do not explode; and (4) the 'onion-skin' layers of massive stars that develop iron cores appear to be an ideal site for explosive nucleosynthesis.
