We study the orbital evolution of hot Jupiters around solar-mass 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. These prescriptions are applied to the models of the rotating stars computed with the MESA code to obtain the tidal dissipation rates, which are subsequently used to simulate the dynamics of a star-planet system until the host's main sequence termination. Special attention is paid to the investigation of the possibility of a star-planet merger since the infalls shape the orbital architecture of Jovian planets in the most straightforward and observable way. Based on our results, we simulate the hot Jupiter population and derive the statistics of planetary infalls within the Galactic thin disk. In particular, we find that coalescence with the MS star occurs for 11 – 21% of the initial hot Jupiter population. Future missions, like PLATO, look promising in terms of the detection of orbital decay.
