Seminar by Yinuo Han, Caltech
Debris disks are frequently observed in planetary systems via dust and gas created by constant collisions between planetesimals and giant impacts involving planets. More recently, facilities such as ALMA and JWST are enabling us to spatially resolve detailed disk structures in thermal emission. This talk will discuss some of the latest findings from these high-resolution imaging campaigns. Particular focus will be given to recent combined analyses of ALMA debris disk programs, including the ALMA survey to Resolve exoKuiper belt Substructures (ARKS), and what these programs reveal about the prevalence of substructures, constraints on planetary populations, and how the structure of debris disks compares to protoplanetary disks from which they form.
