"WitrynaGenerally, we find that the low-mass binary (BWD) mergers do not show pronounced difference in the ISO and in the N-body models. When massive BBHs exist, they dominate the binary heating process by which the dynamical impact on the low-mass binaries is strongly suppressed, as shown in Fig. 4. We expect that the dynamical … " - Impact of core mass on binary evolution

Motivated by this, we discuss the implications of a PPISN happening with a close binary companion and what impact these events have on the formation of merging BBHs through binary evolution. For this, we have computed
