     96A [attachment:press_sonicrad.gif​ movie] of the pressure with overlaid velocity vectors and contours of the sonic surfaces shows the generation of multiple shock layers, both at the surface of the kernel, as well as inside the kernel.
     97
     98The same [attachment:press_sonicrad_zoomout.gif​ movie], but zoomed out, shows that the sonic radius of the Bondi solution is correctly located at $R_s=6$, and doesn't move over time.
     99
     100Finally, we have lineout movies of [attachment:press_lineout.gif​ pressure], [attachment:rho_lineout.gif​ density], and [attachment:vrad_lineout.gif​ vrad]. As these movies show, the Bondi solution is unaltered beyond $r>20$, as to be expected from the boundary conditions of the sim. Also surprising, despite the density falling below its initial value in the kernel (due to accretion), the pressure spikes there seemingly artificially (rather than due to a build of material in the kernel).
