    2727It is 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)].
     
    3131The horizontal line in the following plots is the value of Pcrit, where Pcrit~1.14 Cs^8^/G^3^*M^2^ and characterizes the maximum external pressure a critical BE sphere can withstand before collapsing. Note that both the thermal and ram pressure at the Bonnor Ebert surface, Rbe, is BELOW the threshold under light ambient medium conditions, whereas in the "matched" ambient medium case both of these pressures  EXCEED the threshold.
