Pebble flux evolution for the Outburst-NoVisc model with different particle sizes. Panel a shows the case with R_p = 1 mm particles, panel b the case with R_p = 0.01 mm particles, and panel c shows a simulation with a varying particle size for each pebble component. Increasing the particle size decreases the lifetime of the pebble disk, due to increased pebble drift rates. If the different pebbles species have different particle radii, large particles in the outer disk can drift inward before smaller processed pebbles are first diffused outward and subsequently later drift inward.
