Ilaria Pascucci - April 20, 2018 Scaling Laws in Disks and Exoplanets: Testing Planet Formation Theories Planets are ubiquitous in our Galaxy, in systems far more diverse than predicted by theoretical models that reproduce the properties of our own Solar System. I will discuss how scaling laws between the properties of planet-forming disks and exoplanets are key to identifying the physical processes that shape planetary systems. I will also examine the spread in disk properties relevant to planet formation and make a link to the diversity of planetary systems.
