Percentage of stellar mergers with the primary and secondary stars in a given stellar phase among all the mergers for the CHElOpreMS (fiducial model, left) and CHElOzams (right) models at Z = 0.004. The stellar phases are divided as in Iorio et al. (2023): pre-main-sequence (preMS), main sequence (MS), terminal main sequence (TMS), shell hydrogen burning (SHB), Core helium burning (CHeB), terminal core helium burning (TCHeB), shell helium burning (SHeB), and remnant phase (Rem). The colourbar shows the number of stellar mergers in each bin. We find similar results in the models with Z = 0.001.
