Total energy dissipation rate (in units of 10³⁵ ergs s⁻¹) as a function of the orbital phase for the e = 0.3 set of models. Models with β₀ < 0.80 (blue) show a relatively narrow periastron effect with a single peak centered in phase slightly after periastron passage. Models with β₀ ≥ 1.20 show a significantly broader periastron effect with a structured peak. Models with 1.20 ≤ β₀ > 0.80 tend to have a dominant peak after periastron and multiple weaker peaks at other phases. Left: all models of the set. Right: models with 0.60 ≥ β₀ ≤ 1.40, which have the weakest energy dissipation rates and are plotted on a scale that shows the variations associated with the tidally excited oscillations.
