Evolution of the inertial-frame mode frequencies σ in units of the dynamical frequency Ωdyn (top panel) and the absolute value of the ℓ = m = 2 tidal overlap coefficients Qℓ,m (bottom panel) for the set of f-modes and i-modes we include during the pre-MS to MS evolution of the Prot,0 = 5 day (left) and 1 day (right) sets of stellar models. In the bottom panel, a subset of these modes are plotted. For the Prot,0 = 1 day models, i-modes that experience avoided crossings are plotted with a circle marker in the bottom panel. -- astro-ph.EP

Tidal Migration Of Exoplanets Around M-dwarfs: Frequency-dependent Tidal Dissipation

The orbital architectures of short-period exoplanet systems are shaped by tidal dissipation in their host stars.
