Top panel: in full lines, we present the distribution of specific energy changes in the interacting stars, where the colors correspond to different times throughout the run. The dash-dotted lines represent the expected typical specific energy changes of a star ejected by the binary at each time interval, given by Eq. (11). The red dashed line corresponds to the cut-off value we use to define the high-energy tail. Bottom panel: time distribution of the most energetic interactions for each interacting star, given in Myr since t₀. In gray, the hardening rate (s) is given as a measure of energy extracted from the binary by the interaction. We notice that while the number of encounters decreases, the hardening rate remains largely constant.
