Abstract:	Models of the lifecycle of dust in the local ISM predict comparable contributions of silicates from low- and intermediate-mass stars, in contrast to findings from meteoritic data. These models rely on calculations of dust condensation in the stellar winds of stars in standard interstellar conditions. In this work, we consider that massive AGB stars can be members of their parent star clusters. Using N-body models of the dynamical evolution of star clusters, we find that 70% of massive AGB stars evolve in clusters, where they are irradiated by the strong intra-cluster UV radiation field. We find that the photodissociation radii of SiO molecules in the majority of AGB stars with mass gtrsim 5 M☉ in star clusters lie within the dust formation zone.
