Abstract:
Theoretical nucleosynthetic yields from supernovae are sensitive to
both the details of the progenitor star and the explosion calculation.
We attempt to comprehensively identify the sources of uncertainties in
these yields. In this paper we concentrate on the variations in yields
from a single progenitor arising from common 1D methods of
approximating a supernova explosion. Subsequent papers will examine 3D
effects in the explosion and the progenitor, and trends in mass and
composition. For the 1D explosions we find that both elemental and
isotopic yields for Si and heavier elements are a sensitive function
of explosion energy. Also, piston-driven and thermal bomb-type
explosions have different yields for the same explosion energy. Yields
derived from 1D explosions are nonunique.
