Survival of Interstellar Organics in Protoplanetary Disks: Laboratory Experiments on Organic Ice Photostability

Following the collapse of a cloud core to form a star, the organic-rich icy grains can become incorporated into planet-forming disks, and the presence of large quantities of organic molecules may radically change the chemical trajectory of a forming planet or moon. It is currently unclear if these interstellar organic inventories survive the…
