Column density profiles for prograde (left) and retrograde (right) circumbinary disks once they have each reached a quasi-steady state. In each panel, the left cyan point represents the primary, and the right cyan point represents the secondary. In the prograde case, we see a large inner cavity has been evacuated, which is punctuated by a stream that feeds the circumprimary disk. The strongest density enhancement in this case occurs at a radius of around 4–5 a_b. In the retrograde case, the disk extends much closer to the binary with a ring-like structure occurring at around 2 a_b with a thickness of around 0.5 a_b. The retrograde disk structure is in better agreement with the observations for DX Cha.
