Gas number density n (upper panels) and neutral fraction XH
(lower panels) at two separate instances around t~4,000 yr. The left panels
show the flow during a central accretion minimum; infalling gas is clearly
visible at r~1.5 x 1016 cm. The right panels show the flow during a central
accretion maximum. The structure near the central axis, in the conical region
marked by dashed lines, is an artifact of our having set the optical depth to
zero along the axis, for R/|z| < tan5°, to avoid numerical issues arising from
the coordinate singularity.
