WebIt was also shown, that the dynamical friction approximation is signiﬁcantly (up to a factor of 10) underestimates the total capture rate for the open cluster. This is caused by the fact, that single-single scattering starts to contribute signiﬁcantly into the cross section at large encounter velocities.
