Resonant behaviour of our simulation 4, binned with stability time (x-axis) and 100 systems per bin. Colour shows for different resonant angles (y-axis) how many systems in the bin are circulating (left panel), librating (right panel) or transitioning between a resonant and non-resonant state (middle panel). We consider the angles in Eqs. (5)−(12) (see Sect. 4.4). Our stability times in simulation 4 stretch between 0.04 Myr up to stable systems after 100 Myr. We see a resonant behaviour in the 2:1 resonant angles where it is common that the systems transition between libration and circulation. However, there seems to be no dependence on stability time with resonances.
