Title: The role of dust in protoplanetary disc evolution
Abstract:
The growth and evolution of dust grains in protoplanetary discs is key to planet formation. While our current understanding is that the evolution of dust grains is controlled by the competition between their growth and radial migration (or radial drift), we do not know how dust is incorporated into planets. A key feature of radial drift is that it leads to differences in the evolution of dust and gas. In this seminar I will demonstrate that this can dominate the evolution of disc composition and discuss how it affects the composition of planets and their host stars. I will then discuss ongoing work using ALMA surveys to better constrain how dust evolves.
