    5050By t=tc~2.3 myr, my [https://clover.pas.rochester.edu/trac/astrobear/attachment/wiki/u/BonnorEbertMatched/ApproxSphereWriteUp.pdf calculations] predicted a density to be of order rho~2.3x10^-21^g/cm^3^. While this is off by ~ 2, it also should be noted that my calculation was considering a shell of mass piling up at the initial Rbe. Since by 2.3 myrs, material has passed within the initial Rbe, my calculation would presumably be larger than observed here.

     52Here is a movie of the density lineout of the BE sphere under matched conditions:

    5256It may be interesting to compare these plots to those of a similar collapse study in which the critical BE sphere in a light medium (same density and homogeneity as in the light ambient of this study) was triggered to collapse with a density enhancement above equilibrium values [https://clover.pas.rochester.edu/trac/astrobear/wiki/u/BonnorEbert#Collapse (click here)] -- <<put a comparison between the times seen in these plots and the times seen there>>.
