Top: comparison of the quality factors Q for terrestrial bodies and Kleopatra, which experience different loading frequencies ξ ≡ 2|ω− n|. Data are from Lainey (2016). For Io and Kleopatra, Q was estimated from Q∕k₂ and k₂ ≐0.3. The value denoted ‘3:2’ was derived for Kleopatra when its moons are locked in the 3:2 resonance (see Sect. 2.6). Similarly, ‘massive’ is for the model with more massive moons (see Sect. 2.7). The dotted line is the expected dependence of Q(ξ) (normalised with respect to the Moon; Efroimsky & Lainey 2007). Bottom: comparison of the ratios k₂ ∕Q and ξ, which are directly constrained by the respective tidal evolution. Kleopatra’s value is slightly above terrestrial bodies.
