Effect of changing the flux factor (β) on nucleation flux ( J) and the grain radius distribution. The lower panel shows nucleation flux for the bin and moment methods for β = 1 and β = 0.0001. For each β value, the bin and moment curves are virtually identical, but the smaller β nucleates further from the star. The upper panel shows the grain radius distributions (again from the bin and moment methods) for β = 1 and β = 0.0001. Decreasing β leads to smaller grains (and a larger number of grains, as the mass contained in grains is the same), but the change is not extreme despite a large variation in β.
