Enhancement of alpha-Elements in Dynamical Models of Elliptical Galaxies

Abstract

In this paper we present a quantitative analysis of the chemical abundances in "monolithic" N-body-Tree-SPH models of elliptical galaxies to determine whether the ratio [alpha/Fe] increases with the galaxy mass as suggested by observational data.
