Fig. 10.

Core-stalling radius as function of N for a particle of mass m_t = 10⁻³M in a cored model (γ = 0, cyan circles) and a mildly cuspy model (γ = 1, red triangles) as extrapolated from Langevin simulations. As in Fig. 6 the dashed lines mark the N^1/2 best fit law in the range 10⁴ ≤ N ≤ 3 × 10⁶.
