Final configurations after 8 Myr of integration of all our simulations with α_mig = 0.0001 and different pebble fluxes. The size of the circle is proportional to the total planetary mass (green) by the third root and to the mass of the planetary core (black) also by the third root. The runs marked with * are the example long-term runs shown in Figs. 8 and 9, while the black arrows indicate the aphelion and perihelion positions of the planet calculated through r_P ± e × r_P. The percentage numbers in front show the pebble-to-planet conversion ratio f_p2p, which is discussed in Sect. 6.
