Normalised final-rotation period P_rot∕P_⋆ as a function of eccentricity (horizontal axis) and ocean depth (vertical axis) in logarithmic scales. Two planets are considered: an Earth-sized planet with six-day (top panels) and one-day (middle panels) orbital periods, and a 10 M_⊕ -super-Earth with a six-day orbital period (bottom panels). From left to right: configurations associated with the values of the Rayleigh drag frequency σ_R = 10⁻⁵, 10⁻⁶, 10⁻⁷ s⁻¹. Values of parameters used for the solid part are given by Table 1. In all cases, the stellar mass is M_⋆ = 0.09 M_⊙, the initial rotation rate is (middle of the interval 0 < σ_2,2 < n_⋆, see Fig. 4), and 10 Hough modes are taken into account in the calculation of the tidal response. The degrees of eccentricity modes causing resonances are indicated in the case of the six-day-period Earth-sized planet with a weak drag(top right panel), consistent with the discussion on Fig. 4.
