Table 2

Initial parameters used for the massive-breakup run.

Debris ring population

Total mass (Mtot) 7 × 1023 kg
Number of initial tracers 200 000
Optical depth ⟨ τ ⟩  = 1 × 10-4

Planetesimal release population

Minimum size 2.06   μm (β = 0.44)
Maximum size 10 cm
Initial size distribution dN ∝ s-3.5ds
Initial total mass 2 × 1022 kg
Initial velocity of mass released Vkep + Δ Vlib / 4
Number of initial tracers 10 000
Initial release distance from the star 35 AU

Notes. All other parameters are identical to those of the fiducial inner-parent-body ring run described in Table 1.
