Relative synodic frequency, ω_s/n = |ω/n − 1| (top), and respective synodic rotation period, P_s = 2π/ω_s (bottom), of the stable asynchronous thermal equilibrium states as a function of the eccentricity for different values of the semi-major axis, a = 0.35,0.4,0.5,0.6 au, corresponding to the stellar masses M_*/M_⊙ ≈ 0.70, 0.73, 0.77, 0.81, respectively. The solid lines give the state with ω/n > 1 (super-synchronous), while the dashed lines give the state with ω/n < 1 (sub-synchronous). These plots are shown on a log-scale in the y-axis.
