Abstract [en]

Fractal grains have a large surface area, which leads to more efficient condensation. The special limiting case where the volume-area ratio is constant (corresponding to, e.g., a very rough grain surface or non-compact aggregates) is particularly interesting, as well as convenient, from a mathematical point of view. If dust grains from AGB stars have 'rough surfaces,' that may have important implications for our understanding of dust and wind formation in AGB stars.
