    <description descriptionType="Abstract">&lt;p&gt;I will&amp;nbsp;present state-of-the art calculations studying tidal dissipation in MKGF stars throughout their evolution. The models incorporate turbulent viscosity acting on equilibrium tides and inertial waves in convection zones, and internal gravity waves in radiation zones, based on our latest understanding of each mechanism. I will use these models to compute tidal evolutionary timescales for the orbital evolution of short-period planets and the spin evolution of the host stars. I will also provide predictions for shifts in transit arrival times due to tidally-driven planetary orbital decay for the closest hot Jupiters that may be detected with NGTS, TESS and PLATO.&lt;/p&gt;</description>
