From small dust to micron-sized aggregates: the influence of structure and composition on the dust optical properties

[Context] Models of astrophysical dust are key to understanding several physical processes, from the role of dust grains as cooling agents in the interstellar medium (ISM) to their evolution in dense circumstellar discs, explaining the occurrence of planetary systems around many stars.

Sumario:[Context] Models of astrophysical dust are key to understanding several physical processes, from the role of dust grains as cooling agents in the interstellar medium (ISM) to their evolution in dense circumstellar discs, explaining the occurrence of planetary systems around many stars. Currently, most models aim to provide optical properties for dust grains in the diffuse ISM, and many do not account properly for complexity in terms of composition and structure when dust is expected to evolve in dense astrophysical environments.
