Abstract

We have intensively followed a sample of SNe type II during their photospheric phase. A single nebular spectra will allow us to complete our analysis with the following results: we will constrain the progenitor mass, estimate the nucleosynthesis yields of e.g., oxygen via detailed spectral modeling, measure the nebular ejecta velocities and line profiles to probe any asymmetries in the explosion mechanism and study circumstellar interaction.
