We present a table giving the yields of 103 isotopes in eight distinct zones in the ejecta from the explosion of a 25 Msun star. Each zone in the ejecta is distinct isotopically due to the evolution and explosion of the star. Thus the table not only gives the yields of isotopes in the different zones of the ejecta but also provides information about the chemical environments in which each isotope is injected into the interstellar medium.
The table is a summary of the nuclear yields from a single numerical model of the explosion of a massive star. The yields from a real supernova will vary from those in this table because of uncertainties in the input physics to the numerical model and because the real star may differ in mass, mass-loss rate, or metallicity from the modeled star. We argue that these uncertainties and variations, for the most part, will not change the direction of the largest isotopic effects in the different zones of the ejecta. This means that the table is quite generally applicable as a guide to understanding the ejecta of supernovae and as a characterization of possible chemical environments in which isotopes are injected into the interstellar medium.
