Left: same as Fig. 4 but for three different temperatures in the H-box. The [Si/Fe] ratio is also shown. Only the final abundance patterns in the box are plotted. The injected species are ¹²C, ¹⁶O, ²²Ne, and ²⁶Mg. Density is unchanged (1 g cm^-3) and the injection rate is 10^-8M_⊙ yr^-1 for ¹²C and ¹⁶O and 10^-10M_⊙ yr^-1 for ²²Ne and ²⁶Mg). Right: same as the left panel but for three different densities in the H-box. The temperature is set to 50 MK.
