Simulations for a = 5 au and r_p = 100 km with the same range in (M_core,1, Σ₁) as in Fig. 2. Orange circles correspond to the solid accretion given by SI08, purple circles to Oligarchic Growth (OG). The darker colours represent all runs that reach Jupiter mass within 10 Myr of disc evolution. The lighter colours highlight the cases that match the meteoritic constraints of K17. Left: total amount of heavy elements accreted until reaching Jupiter mass as a function of the initial surface density of planetesimals (Σ₁). The green shaded area indicates the values of M_Z compatible with estimates from Juno (Wahl et al. 2017). Right: amount of heavy elements accreted during the detached phase with the different solid accretion prescriptions.
