PPI-driven mass loss as a function of the CO core mass. Top panel: total mass ejected in pulses, bottom panel: mass lost in individual pulses. The amount of mass lost does not have a monotonic behavior with pulse number, and spans a wide range of values. The first pulse is shown as a blue dot, and the second and third, if they occur, are shown as a purple plus and red cross, respectively. Thin vertical lines connect multiple pulses for the same M_CO.
