Post-formation entropy distributions. Left panel: Post-formation entropy s₀ as a function of planet mass. The black dots show s₀ predicted by core accretion planet formation simulations in the New Generation Planet Population Synthesis NGPPS (Emsenhuber et al. 2021b). Grey dots are the s₀ in the nominal case (Eq. A.1). The coloured lines finally represent the four parameterisations used in this appendix, which are a generalisation of Malsky & Rogers (2020). Right panel: Kernel density estimation of the distributions of s₀ in the NGPPS of three intervals of the total planet mass. One sees how the mode of the distribution shifts to higher values with increasing planet mass.
