Description
Core-collapse supernovae are one of the most important sources of heavy elements
in the universe. Therefore, accurate modeling of the stellar evolution and the explosion
phases are crucial to obtain accurate predictions of their nucleosynthetic
signature. In this talk I will present results from nucleosynthesis calculations of realistic
neutrino-driven supernova explosions in spherical symmetry. I will comment on the
explosive nucleosynthesis, weak r-process component calculated with realistic neutrino
spectra, as well as the contribution of the pre-supernova seeds to the final yields. As
a representative example, I will discuss Ti44, a radioactive isotope that powers the
late-time light curve of supernovae and whose abundance has been measured in several
supernova remnants. I will discuss different production mechanisms both pre- and postcollapse as well as the potential impact of multi-dimensional effects on its final abundance.
