Example of ejection from a tidal Cassini Equilibrium due to moon inspiral. The color of the curve shows the moon’s distance to the planet; the gray curve shows the evolution after the moon has been lost. The center of the resonance (Cassini state 2; red curve) and its width (pink region) are shown at capture time, when the moon’s semi-major axis is a_m ≈ 25 R_p. Along the dashed black curve, the star-driven tidal dissipation results in $\dot{\omega }=0$ (see Eq. (8)).
