Confidence limits of SN, Kinetic Energy and chemical yields in evolutionary synthesis models

Abstract

When evolutionary synthesis models take into account the stochastic nature of the IMF together with the discrete number of stars in real stellar clusters, typical output turns to dispersion band (where real data can be placed) instead of narrow lines. We present here a qualitative analysis of such dispersion in the SN rate, the kinetic energy and the 14N/12C ratio for different amounts of mass transformed into stars.
