Chemodynamical Simulations of Dwarf Galaxy Evolution

Figure 2

The effect of the IMF on the evolution of galaxies. (a) The adopted SFR (upper panel), together with the upper stellar mass (in , middle panel) and the average slope of the IMF (in number, lower panel) calculated for the IGIMF galactic model (red lines in the right panels). (b) Predicted evolution of abundance and abundance ratios for a IGIMF galactic model (red lines). Plotted are the evolution of oxygen (upper panel), carbon-to-oxygen ratio (middle panel), and nitrogen-to-oxygen ratio (lower panel). The black line represents the evolution of a model with a time-independent Salpeter IMF (i.e., with a slope of −2.35).
