Energy dissipation rates of the previous figure but here plotted as a function of the periastron distance, r_per. In this representation, the different curves for each eccentricity “collapse” onto a common region. The dashed lines show the absolute value of Ė_orb given by Eq. (A31) of Hut (1981) for e = 0.1 and 0.8, also plotted as a function of r_per. Symbols correspond to the different eccentricities: e = 0.00 (open triangles), 0.01 (filled triangles), 0.10 (small pentagons), 0.30 (large pentagons), 0.50 (crosses), 0.70 (stars) and 0.8 (filled pentagons).
