Among various mechanisms, tidal interaction plays a critical role in its impact on the dynamics of close-in planetary systems. This is especially true for systems with hot Jupiter, as tidal dissipation provides rapid migration of the most massive planets leading to their engulfment. We study the orbital evolution of hot Jupiters around solar-mass pre-main sequence (PMS) and main sequence (MS) stars following the tidal prescriptions from Barker (2020), allowing to investigate the dissipation of equilibrium tide, inertial waves, and gravity waves over the wide parameter space. Based on our results, we simulate the hot Jupiter population and derive the statistics of planetary infalls within the Galactic thin disk.
