Description
The irregular dwarf galaxies IC 10 and IC 1613, located in the local group and lacking evidence of interactions, offer ideal environments to study star formation in low mentalicity region, chemical enrichment, and r-process elements production. We adapt the galactic chemical evolution (GCE) model OMEGA (Côté et al. 2015, 2016) to reproduce observed properties of these galaxies, including gas and stellar mass and the evolution of alpha elements such as oxygen and magnesium. The model is then extended to explore the enrichment history of r-process elements like europium. The model inform key parameters such as star formation efficiency, inflow, and outflow rates. Using previously established results, particularly those from Yin et al. (2010), as a reference framework, our model offers new insights into nucleosynthesis and feedback in low-metallicity systems. Preliminary results underscore the role of metal-enhanced winds and highlight these galaxies as promising sites to study isolated r-process enrichment beyond neutron star mergers.
