Internal structure and tidal dissipation evolution for a M_ZAMS = 2 M_⊙ star. Top left: Kippenhahn diagram. The brown hatched regions represent convective layers, and the yellow dotted region represents radiative layers. Stellar evolutionary phases (PMS to WD) are indicated. Top right, bottom left, and bottom right: Complex part of the Love number for the equilibrium tide (Im(k₂²)_eq), the dynamical tide (Im(k₂²)_IGW), and the ratio of the dissipations of the dynamical tide to the dissipation of the equilibrium tide (Im(k₂²)_IGW/Im(k₂²)_eq), respectively, as a function of stellar age and orbital period. The Roche limit is shown in purple, the critical period (1/ν_c; see Eq. 6) in orange, and the period at which a planet orbits at the stellar radius in brown. Changes in the stellar evolutionary phase are indicated with ticks on the upper axis.
