Disk Galaxy Models Driven by Stochastic Self-Propagating Star Formation

open access: yesOpen Astronomy, 2010
We present a model of chemical and spectrophotometric evolution of disk galaxies based on a stochastic self-propagating star formation scenario. The model incorporates galaxy formation through the process of accretion, chemical and photometric evolution ...

Modeling the chemical evolution of the Galaxy halo [PDF]

open access: yesAstronomy & Astrophysics, 2013
We study the chemical evolution and formation of the Galactic halo through the analysis of its stellar metallicity distribution function and some key elemental abundance patterns. Starting from the two-infall model for the Galaxy, which predicts too few low-metallicity stars, we add a gas outflow during the halo phase with a rate proportional to the ...

PN-Carbon Yields and the Chemical Evolution of the Galaxy [PDF]

open access: green, 2001
Two sets of observational carbon stellar yields for low-and-intermediate mass stars are computed from planetary nebulae abundances derived from C II $\lambda4267$ and C III $\lambda\lambda1906+1909$ lines, respectively.

The Chemical Evolution of Galaxy Disks

open access: green, 2000
We discuss the main ingredients necessary to build models of chemical evolution of spiral galaxies and in particular the Milky Way galaxy. These ingredients include: the star formation rate, the initial mass function, the stellar yields and the gas flows.

Chemical Evolution of Clusters of Galaxies

open access: green, 2001
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 toy-model to follow the chemical evolution of the ICM, formulated in analogy to chemical models for individual galaxies.

Chemical Evolution of Galaxies and Intracluster Medium [PDF]

open access: green, 2002
In this series of lectures I discuss the basic principles and the modelling of the chemical evolution of galaxies. In particular, I present models for the chemical evolution of the Milky Way galaxy and compare them with the available observational data.
