Top: accretion and specific orbital angular momentum profiles of the accretion burst at the first periastron passage. The profile is smoothed by taking a moving average over a window of 10 yr. The dashed line in the top panel shows the separation of the binary. In the bottom panel the momentum is plotted for the primary and secondary star. The vertical dotted lines indicate the times when density slices were taken, which are shown in the bottom figure. Bottom: zoomed-in slices of the high-resolution simulation of the T2 scenario with L_ref = 14. The slices are produced with the same methods as Figs. 1 and 2 but with a projection thickness of 30 AU. The black circles show the accretion radius of the stars. The solid lines are density contours spaced evenly in log-space at density =[0.5, 1.3, 3.2, 7.9, 20, 50]×10⁻¹² g cm⁻³.
