Evolution of the feedback products ejected by a representative star cluster (black line), with contributions of its three stellar populations shown as blue, orange, and green lines. Top: mass-loss rate due to CC SNe and OB/AGB winds. Middle: bolometric (solid) and ionizing (dashed lines) luminosities. Bottom: energy injected by CC SNe events (solid lines) as well as the continuous kinetic energy injected due to OB/AGB mass loss (dashed–dotted lines). Dotted vertical lines indicate events of mass growth for the star cluster and are labeled in the top panel.
