Specific mass of dust produced and/or destroyed as a function of time. Upper panel: overall evolution of dust computed as the enrichment from stars minus the dust removal from different mechanisms. We show cases with and without dust growth in the ISM. The initial mass of the gas is equal to four times the final mass of stars, Mgas,ini = 4 × M*,fin and τ = 1000 Myr in Eq. (8). Middle and lower panels: Dust removal due to different mechanisms included in the models in the upper panel, as mentioned in the legend, where “PE” stands for “photo-evaporation”.
