Top row: large-scale equatorial slice of the gas surface density with associated equatorial velocity flow (white quivers). A dashed white line indicates the azimuth of the main streamer, for which poloidal slices are performed. Middle row: large-scale poloidal slice of the gas particle density with associated poloidal velocity flow (white quivers). Bottom row: large-scale poloidal slice of the gas poloidal velocity, normalized by the free-fall velocity, with associated poloidal velocity flow (white quivers). Each column corresponds to a late time snapshot, respectively at 60 (left column) and 70 kyr (right column). In each plot, a line integrated convolution treatment is applied to emphasize the gas streamlines. The innermost 100 au are masked by a gray circle to allow for adequate contrast.
