Energy dissipation rates (in erg s^-1) from our model calculations for β₀ = 1.2 and different eccentricities as indicated. The dashed lines show the absolute value of Ė_orb given by Eq. (A31) of Hut (1981), as written in our Eq. (30). The dotted lines connect the points corresponding to each eccentricity. The short dot-dashed lines show the values of Ė_Hut for e = 0.8 and lag angles α = 10° and 50°.
