| Abstract: | Two of the basic building blocks of galaxies are stars and the interstellar medium. The evolution of the abundance composition
in the latter and especially the enrichment of heavy elements as a function of space and time reflects in turn the history
of star formation and the lifetimes of the diverse contributing stellar objects. Therefore, the understanding of stellar evolution
and its endpoints (mainly planetary nebulae, supernovae of type Ia and type II/Ib/Ic) is essential. Despite many efforts,
a full and self-consistent understanding of supernovae (the main contributors to nucleosynthesis in galaxies) is not existing,
yet. However, they leave fingerprints, seen either in spectra, lightcurves, radioactivities/decay gamma-rays or in galactic
evolution. Here we want to address the composition of ejecta, their model uncertainties and relate them to constraints from
abundance observations in galactic evolution.
