Sizes (radius) of the different dust species (listed in the legend) formed in the wind of AGB stars as a function of the current stellar mass. The left and right panels refer to the Z = 0.03 and Z = 0.04 metallicities, respectively. For the sake of readability, we only show the 1.25 M_⊙ and 3 M_⊙ cases for the low-mass domain (top panels), and the 4 M_⊙ and 7 M_⊙ models for the HBB domain (bottom panels).
