Generated tidal heat flux as a function of the mantle temperature (T_m) and the log of the asthenosphere’s (η_α) and mantle viscosity (η_m). Stable and non-stable equilibria points are shown as black and gray dots, correspondingly. At a non-stable equilibrium point, a deviation in the mantle temperature drives the moon out of equilibrium, whereas a body at a stable thermal equilibrium state tends to restore its equilibrium. The tidal heat flux was calculated for a moon with a semi-major axis of a = 6.59 Roche radii, e = 0.02, α = 0.5, and B = 30 with the rest of the sensitivity parameters set to their nominal values (Table 2).
