Evolution of the gas and protostellar mass in the simulations with different temperatures (top panel). Comparison of the time evolution of the MMO mass and the total mass of the protostars without the MMO (second panel), accretion rate of the MMO with the mean accretion rate of the protostars without the MMO (third panel), where the black dashed line is the critical accretion rate ṁ_crit = 0.04 M_⊙ yr⁻¹ and marks the point where the protostars pass to the SMS Track. We further show the radius of the MMO with the mean radii of the protostars (fourth panel) and the evolution of the total collision rates over time (bottom panel).
