Planets Across Space and Time (PAST) VI: Age Dependence of the Occurrence and Architecture of Ultra-Short-Period Planet Systems

This conference talk explores the "Age Dependence of the Occurrence and Architecture of Ultra-Short-Period Planet Systems" as part of the Planets Across Space and Time (PAST) research series. Presented by Pei-Wei Tu from Nanjing University at the Kavli Institute for Theoretical Physics' "Planets on the Edge" conference, the 17-minute presentation examines how ultra-short-period exoplanets—Earth-sized rocky planets with no Solar System counterparts—evolve and occur across different stellar ages. Learn about discoveries from the Kepler and TESS missions that challenge our understanding of planetary formation, addressing key questions about the nature of close-in rocky planets, their formation mechanisms, system variations, and their absence in our own Solar System. This talk contributes to the broader conference goal of synthesizing knowledge about inner disk properties, advancing planet formation models, and fostering interdisciplinary collaboration among experts in exoplanet demographics, protoplanetary disks, and meteoritics.
