Three-dimensional view of the inner disk and protostar at a moment in time when the former has reached ≈0.5 AU in radius. The blue structure is the surface of the inner disk. The inner r < 0.1 AU region has been cut out in order to reveal the flow onto the protostar (rendered in green). The white curves are velocity vector field streamlines launched along the poles to reveal polar accretion. The bottom, left, and right panels are cross sections through the center of the domain displaying the radiative flux. The visualized volume is 1.6 × 1.6 × 1.6 AU³. An animated version of this plot is available online.
