Self-gravitating simulations with R = 0.005 (corresponding to a physical radius of 1 km in the Chariklo case), assuming particles with bulk density ρ = 300 kg m⁻³. The initial distribution extends to r = 1.55–2.8, which corresponds to the range r_h = 0.75–1.35. With N = 24 000 particles the initial τ₀ = 0.11. The upper row shows two snapshots of the simulation with no mass anomaly, while the lower row shows a simulation with a µ = 0.3 mass anomaly. The location of the 1/3 SOR (a = 2.08) corresponds to r_h ≈ 1.0. In the T = 20 frames, the tick marks on the right vertical axis indicate the radii where r_h = 1.15. The red and green solid lines in the µ = 0.3 frames indicate the locations of 1/2 (left) and 1/3 (right) SOR. The insets in the T = 150 frames zoom in on the largest aggregate formed during the run, covering a 0.4 × 0.4 region with a correct aspect ration. The slice of the aggregate through the z = 0 plane is shown.
