A chemical evolution model for galaxy clusters
L. Portinari, A. Moretti, C. Chiosi
We develop a toy-model for the chemical evolution of the intracluster medium, polluted by the galactic winds from elliptical galaxies. The model follows the "galaxy formation histo…
Chemical Evolution of Clusters of Galaxies
L. Portinari, A. Moretti, C. Chiosi
The high metallicity of the intra-cluster medium (ICM) is generally interpreted on the base of the galactic wind scenario for elliptical galaxies. In this framework, we develop a t…
Dwarf Elliptical Galaxies: Structure, Star Formation, and Color-Magnitude Diagrams
G. Carraro, C. Chiosi, L. Girardi +1
The aim of this paper is to cast light on the formation and evolution of elliptical galaxies by means of N-body/hydro-dynamical simulations that include star formation, feed-back a…
Zero-metallicity stars I. Evolution at constant mass
Paola Marigo, Leo Girardi, Cesare Chiosi +1
We present extensive evolutionary models of stars with initial zero-metallicity, covering a large range of initial masses (i.e. 0.7 <= M <= 100 Msun). Calculations are carried out…
