Time evolution of the mass-weighted disk eccentricity and the mass weighted longitude of pericenter for the fiducial model. The disk has the lowest eccentricity and has the least variation during one binary orbit when the longitude of pericenter is aligned with the binary periastron (ω_d = ± π). From that point the disk’s eccentricity and variation during one binary orbit increases and reaches a maximum when the longitude of pericenter is aligned with the binary apastron (ω_d = 0).
