Imaginary part of the Love number, Imk₂, as a functionof the excitation frequency assuming α = 0.25. Full lines: Imk₂ as calculated by the profiles of Dumoulin et al. (2017) for the two different models (hot: orange, cold: blue). Dashed lines: best fit of Imk₂ for a homogeneous body. Dotted lines: obtained with the averaged values of μ and η from Fig. 4. The black vertical dashed line represents the excitation frequency of Venus (ω_Venus = 2(n_Venus − Ω_Venus)).
