Main channels for “late” core-collapse supernovae in our standard simulation and their relative contribution to the number of late events (only showing those that contribute >5% of the number of late ccSNe, i.e., >0.75% of the total number of ccSNe). For merger channels, we indicate the evolutionary state of the primary and secondary star at the onset of merging. Arrows indicate the direction of mass transfer preceding the merger, which can be forward (from primary to secondary) or reverse (from secondary to primary). MS: main sequence; HG: Hertzsprung gap; COWD and ONeWD: carbon-oxygen and oxygen-neon-magnesium white dwarf; HeStar: naked helium star; AGB: Asymptotic Giant Branch.
