Planetary growth tracks, mass over time, and semimajor axis evolution for a giant planet system. The system that is studied leads to a gas giant planet of 997.6 M⊕ for the ΣP ∝ r−2.1 density distribution and a 281.7 M⊕ planet for the dynamic model. The other systems lead to 51.1 M⊕ for ΣP ∝ r−1.5 and 4.64 M⊕ for ΣP ∝ r−0.9. Upper panel: mass and semimajor axis change during the evolution of the system, while middle panel: growth of the embryo over time. Lower panel: semimajor axis evolution over time. On timescales of million years, the giant planet in the dynamical planetesimal formation and the ΣP ∝ r−1.5 simulation falls into the star due to tidal forces, which is no longer shown in the lower right panel.
