Title: Migration, Tides, and the Diversity of Extrasolar Worlds
Abstract: A large fraction of exoplanetary systems contain planets orbiting close to their host stars, with orbital periods of only days to weeks. These planets experience strong tidal forces that can reshape both their orbits and interiors. Energy dissipated by time-dependent tidal deformations can drive orbital migration and heat planetary interiors, producing potentially observable signatures. In this talk, I will explore several outstanding puzzles in the demographics of short-period exoplanets and show how tidal evolution offers a compelling explanation. I will also highlight how new observations with JWST can test these tidal theories and illuminate the role of tides in shaping the remarkable diversity of close-in planetary systems.
