Schematic presenting a description of our set of nine simulations. The heavy belt cases are at the top (compact configuration) and middle (extended configuration), and the light cases are at the bottom. Jupiter, Saturn, Uranus, and Neptune are designated by J, S, U, and N, respectively. The different simulations differ in terms of the locations of planets, accretion efficiency, the viscosity of the gas, and the belt’s mass. For the heave belt configurations, the time when depletion starts is also a parameter. Each parameter has its own symbol and colour as can be seen in the bottom part of the image.
