He abundances in disc galaxies
Astronomy & Astrophysics, 2019We investigate how the stellar and gas-phase He abundances evolve as a function of time within simulated star-forming disc galaxies with different star formation histories. We make use of a cosmological chemodynamical simulation for galaxy formation and evolution, which includes star formation as well as energy and chemical enrichment feedback from ...

Chemical Abundances and Galaxy Evolution
1984The chemical abundance characteristics of two comparatively structurally simple classes of galaxies, the ellipticals and irregulars, are briefly reviewed. Neither of these types of galaxies have properties which are fully consistent with the quantitative predictions of basic chemical evolution models. Possible sources for discrepancies are discussed in

Abundance Gradients in Spiral Galaxies
1997The study of HII regions in the disks of spiral galaxies has given us important information about their physical conditions. In particular the study of their chemical abundances soon showed the existence of negative gradients with higher abundance towards the centre of a galaxy (e.g. Pagel and Edmunds 1981; McCall 1982; Diaz 1989; Dinerstein 1990).
