Disk aspect ratio h ≡ H/R measured 20 kyr after the infall has stopped (t = 28 kyr), for ﹩{\dot{M}}_{{\rm{in}}}=1{0}^{-7}\,{M}_{\odot }\,{{\rm{yr}}}^{-1}﹩ (left) and ﹩{\dot{M}}_{{\rm{in}}}=1{0}^{-6}\,{M}_{\odot }\,{{\rm{yr}}}^{-1}﹩ (right). The contour lines correspond to h = 0.05–0.30, in increments of 0.05. As the streamer excites greater eccentricity, the disk aspect ratio becomes increasingly nonaxisymmetric, persisting even ∼20 kyr after the infall has ended.
