Fig. 6


Full planetary formation, now allowing for the migration of the embryos, for different radii of the accreted planetesimals (red, 100 km; blue, 10 km; green, 1 km; orange, 0.1 km). The same line code as in Fig. 3 is adopted. Embryos are initially located at 6 AU. The left panel shows the cumulative mass of the embryo (solids plus gas) as a function of time (in logarithmic scale). The right panel depicts the migration path of the protoplanet (in linear scale). For the accretion of 1 km planetesimals, the embryos are lost in the Sun (indicated with crosses in the plot). The same happens for the planet that grows by accretion of 0.1 km planetesimals in the equilibrium approximation (orange solid line). When planets are lost, calculations are stopped.
