Global mass-weighted disk eccentricity (top) and disk periastron (bottom), both sampled at the binary’s apastron, for isothermal simulations of the standard model with different aspect ratios H/r. The disk eccentricity needs quite a long time to reach a quasi-equilibrium and settles at around 0.2 for an H/r of 0.05 and 0.055. High values of H/r result in a lower disk eccentricity. Note that in the lower panel a short time span is displayed for clarity.
