Comparison of timescales for resonant trapping from simulation data (black dots) with the median values (solid black lines) and 1σ uncertainties (gray bands), against the collisional timescale corresponding to the maximum resonant ring optical depth of τ_BG ∙ ⟨C_τ⟩ (dashed purple lines). For each ⟨C_τ⟩ value of ∼2, 6, 8, and 10 for F, G, K, and M-types stars, τ_BG values of 3 (upper dashed line) and 27 zodis (lower dashed line) are examined (see Sect. 3.2.2). Other plotting conventions are identical to those in Fig. 11.
