Total energy dissipation rate (in units of 10³⁵ ergs s⁻¹) as a function of the orbital phase for the e = 0.5 (top) and e = 0.7 (bottom) models. All β₀ values modeled are plotted on the left while on the right we zoom in on the 0.80 ≤ β₀ ≤ 1.40 cases. Although the orbital elements are all the same in these models, the perturbation duration around periastron differs, being longer for faster rotation rates (larger β₀ values). The lowest-lying curves are those for β₀ = 1.00 (green), 1.05 (red dash) and 1.10 (red dot), all of which display several discrete peaks between orbital phase 0.9−1.3.
