Scientific paper

In this paper we discuss the chemical enrichment in galaxies from type I supernovae and novae. Both type Ia supernovae and novae are believed to originate from white dwarfs in binary systems; therefore, their progenitors are low and intermediate mass stars. We show that type Ia supernovae are the most important producers of iron in galaxies whereas novae can be important producers of 7Li, 15N and 13C although many uncertainties in nova nucleosynthesis are still present.
