Mass vs. semimajor axis of synthetic planet populations for different ΣP distributions after 100 million years. Each setup contains one single planetary embryo. The initially set distributions for ΣP are ΣP = Σ0r−0.9 (initial gas density slope), ΣP = Σ0r−1.5 (mmsn) and ΣP = Σ0r−2.1 (Lenz et al. 2019). Bottom right panel: population in which planetesimals form over time using the model described in Sect. 2. The circles given around the data points show the mass fraction of envelope mass over core mass. The numbers of systems are 1999 (ΣPr−0.9), 1990 (ΣPr−1.5), 1961 (ΣPr−2.1), and 1945 (ΣP- dyn).
