Explore the fascinating process of planet formation in this lecture by Dr. Andrea Banzatti from the Space Telescope Science Institute. Dive into the mystery of how planets acquire their solid and gaseous components, and discover how the composition of protoplanetary disks influences the creation of diverse worlds. Learn about the advancements in studying circumstellar disks over the past two decades, particularly following the discovery of exoplanets. Examine the challenges faced by both theories and observations in understanding the connection between exoplanets and protoplanetary disks. Gain insights into star formation, the first exoplanets, theoretical models, classical problems in planet formation, dust traps, new observations, and the concept of the snow line. Recorded live at the Space Telescope Science Institute, this comprehensive talk offers a deep exploration of the cutting-edge research in planetary science and astrophysics.
