Top-down (top row, panels a–e) and edge-on (bottom row, panels f–j) slices through the center of the domain of run G1 displaying density and velocity streamlines. The color coding in the velocity streamlines displays the local radial mass flux −ρv_r. Each column displays a different epoch, where t = 0 (panels b and g) corresponds to the moment of protostellar breakup. The scale bar in panel a applies to all other panels. An animated version of this plot is available online.
