Chemical consequences of low star formation rates: stochastically sampling the IMF
L. Carigi, X. Hernandez
When estimating the abundances which result from a given star formation event, it is customary to treat the IMF as a series of weight factors to be applied to the stellar yields, a…
Enrichment of the Intergalactic Medium by the Milky Way Subgroup
Leticia Carigi
I study the effect of the galaxies of the Milky Way subgroup on the chemical enrichment of the diffuse gas within the Local Group. The preferred model predicts that the present-day…
Photometric Constraints on Chemical Evolution Models of Irregular Galaxies
Leticia Carigi, Gustavo Bruzual
Photometric properties of stellar populations that evolve according to chemical evolution models developed by Carigi, Colin, & Peimbert (1999) and Carigi & Peimbert (2001) are expl…
Some Implications of Galactic Abundance Gradients Derived from H II Regions and Planetary Nebulae
Manuel Peimbert, Leticia Carigi
By comparing observed abundance gradients with those predicted by a chemodynamical model of the Galaxy the following results are obtained: there is a defficiency of O/H poor PNe in…
Dark Matter and the Chemical Evolution of Irregular Galaxies
L. Carigi, P. Colin, M. Peimbert
We present three types of chemical evolution models for irregular galaxies: closed-box with continuous star formation rates (SFRs), closed-box with bursting SFRs, and O-rich outflo…
Chemical Evolution of Irregular and Blue Compact Galaxies
L. Carigi, P. Colin, M. Peimbert +1
We discuss the chemical evolution of metal poor galaxies and conclude that their oxygen deficiency is not due to: the production of black holes by massive stars or a varying slope…
