Event Details & Abstract: 

Powerful telescopes such as ALMA and VLT/SPHERE, with their unprecedented sensitivity and spatial resolution, are revealing fascinating structures in protoplanetary disks at different wavelengths, including: multiple rings, vortices, asymmetries, dips of emission, and spiral arms. In this colloquium, I will compare these observations with theoretical models that combine hydrodynamical simulations of gas evolution and dust growth, which include the coagulation and fragmentation of particles. I will present how these detailed observations are providing significant insights about how different physical conditions rule the evolution of protoplanetary disks, such as snow lines, potential embedded planets, and viscosity. This bridge between models and observations is extending our understanding of how planets form and allowing us to understand the large diversity of configurations of extrasolar syst
