Expulsion of dust aggregates from galaxies

In this paper we analyse the possibility of dust being repelled away from a galactic disk by radiation pressure exerted by starlight, studying the effect of a grain aggregate model for the dust. It was found that the aggregated structure enhances the effect of radiation pressure.
