Temporal evolution of orbits with a = 1800 au. The initial conditions are I = 0o, and ϖ = ω + Ω equally distributed in [0, 2π]; the initial value qi of the perihelion distance is written on the right of each graph. The vertical black line marks the 4.5 Gyrs time, at which our density maps (e.g. Fig. 17) are computed.
