    9898The [attachment:press_sonicrad_zoomout.gif​ same 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.

    100 Finally, 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. Surprisingly, however, is that 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).
