Fig. 2
Cold disc (50 ≤ r ≤ 90 au) of an A6V star: normalised disc-integrated particle size distribution at collisional steady state for a “bright” debris disc with fd ~ 10−3, and a “very bright” debris disc with fd ~ 5 × 10−3. The red line corresponds to a simulation that only takes s ≥ sblow grains into account. The vertical dotted line corresponds to the blow-out size sblow.
