Averaged multiplicity fraction as a function of primary mass of systems for primary mass ≥ 5 M_⊙ from three models (MS3OP_SP, MS3OP_SPC, and MS3OP). Black triangles and red circles are the multiplicity fractions of systems that remain in the cluster and of the dynamically ejected systems, respectively. Model names are indicated at the top of subfigures. Grey hatched area indicates where a primary mass is higher than 62.4 M_⊙, that is, the evolved mass of a m_max star (79.2 M_⊙ at t = 0 Myr) at 3 Myr, evolved by single stellar evolution. Primary stars of all systems inside the area are therefore stellar mergers. Technically, these stars are blue stragglers that lie above the main sequence (cf. Dalessandro et al. 2013).
