The chemistry of protoplanetary disks
Year: 2025
Type: article
Abstract: The chemistry of protoplanetary disks is central to understanding the origins of planetary systems and, ultimately, the potential for life. This review talk will present the state of the art in the study of disk chemistry, surveying the latest insights into the formation and evolution of chemical species in the different disk's regions, from the cold outer zones to the warmer inner regions. I will discuss how recent progress in observational techniques, including ALMA and JWST, have provided unprecedented detail in identifying molecular species, tracing chemical gradients, and better understanding disk dynamics. I will highlight the interplay between gas-phase and solid-state chemistry, how stellar radiation impacts the chemistry and molecular distribution, and the role of disk dynamics and dust grain evolution in setting disk chemical makeup. I will also pinpoint key open questions in the field, such as the interstellar inheritance, the potential mechanisms driving complex organic molecule formation in such environments, and the influence of disk chemistry on planetary composition. These topics, among others, will serve as focal points for discussion, fostering dialogue on bridging gaps in our understanding of these primordial chemical environments. This last session will aim to encourage collaborative discussion on the future directions of protoplanetary disk chemistry, focusing on the observational and modeling efforts needed to tackle outstanding questions in the field.
