Relative mass evolution of the Oort cloud and detached population. For isolated clusters the mass evolution of the Öpik-Oort cloud, Oort-Hills cloud, and the detached populations are given by the upper red, blue and orange symbols, respectively. The triangles give the mass evolution in the simulation where the Solar System left the cluster 20 Myr after the formation of the giant planets, the bullets for the isolated Solar System. Here we adopted the inner Öpik-Oort cloud boundary of r_inner = 30 000 au. The red symbols are identical to the blue and red dots in the main paper’s Fig. 1. The two solid red curves represent the fits to the two Öpik-Oort cloud populations.
