Initial mass function peak prediction from protocluster model with isotropic turbulence for cloud-cluster mass ratio α_{∗ ,c} = 1,2,3 plotted against protocluster mass. The values 1 and 0.7 are used for the Larson relation ρ ∝ R^{− γ}. As for the polytropic index Γ of gas inside the protocluster, values 1 (isothermal) and 0.85 are considered. The Jeans mass is plotted with thin curves, and the IMF peak mass is plotted with thick curves. Color codings are same as those in Fig. 6.
