Chemodynamical Simulations of Dwarf Galaxy Evolution
Figure 1
The effect of the temperature threshold above which star formation is not allowed. (a) The density distribution of gas in two runs with different : K (left panels) and K (right panels). The four rows are snapshots of the evolution of the two models at four different moments in time: 50 Myr (uppermost panels), 100 Myr (second row of panels), 150 Myr (third row of panels), and 200 Myr (lowermost panels). Dense gas is in orange (upper densities are 10−23 g cm−3); dilute gas is in blue (lower densities are g cm−3). (b) Star formation rates (in ) and global metallicities (in ) for the same models shown in the left panels, during the first 200 Myr of galactic evolution.
