    191191  In Figure 4 for even stronger compression, the compression wave is now evident in the plots. I see in their velocity plots a turn-over similar to wee see for the different phases of evolution. The last plot they show before the sink forms, seems to be indicating a compression wave is about to "converge on the center". However, we also saw this type of evolution, but between this time and sink formation in our runs, the density profile evened out to a collapsing BE profile. I wonder if Hennebelle et al found similar results, and if so, why they did not choose to report it... This case seems most like our Matched case.

    193196  In Figure 5, the compression wave seems to completely rip through the BE sphere, although no mention of the speed of the incoming compression wave is given (which would have been interesting to compare to the triggered star formation stuff Shule has been looking at, which for mach > 20 has been shown to disrupt the BE sphere from being able to form a sink). It seems like the compression wave keeps building mass because of the abrupt increasing change in Pext that adds density to the wave in an isothermal fashion.
