Dust and pebble mass evolution for different parameters. The dashed (dotted) line corresponds to enlarged (lowered) values by the variation indicated in Table 1. All simulations were performed using the nominal dust photoevaporation model and including removal and Poynting–Robertson drag of dust due to radiation pressure. The top row shows the influence of dust-evolution parameters, the middle row shows results for varied initial disk conditions, and the bottom row shows simulations with different gas-evolution parameters. For several parameters, radiation-removed masses lie below 1 × 10⁻² M_⊕ and are, therefore, not visible.
