    Institution: WiCOR, UW–Madison Title: Modeling the Chemical and Dynamic Feedback Mechanisms of Planet Formation Abstract: Planets form in protoplanetary disks, inheriting the composition of the solids and gas present at their formation location. These PPDs, however, are constantly evolving, with dust growth, fragmentation, and pebble drift driving chemical evolution in the gas. While these effects …
