Effective tidal dissipation and heating as a function of the tidal relaxation time for fixed eccentricities. Top: effective tidal quality factor Q_eff. Bottom: dimensionless tidal heating rate ﹩{\dot{E}}_{{\rm{tide}}}/[{ \mathcal E }{n}_{f}({k}_{f}-{k}_{e})]﹩. The vertical dotted line marks n_fτ_M = 1. Tidal dissipation peaks near the transition between elastic and fluid-like behavior, producing a minimum in Q_eff and a corresponding maximum in heating.
