Meeting update

I've been studying the effects of a heavier medium on the collapse of a BE sphere. The sphere was found to be stable to collapse in a light medium (1/100 the density of the sphere's outer edge), but collapsed fairly quickly in the case where the density matched the sphere's outer edge. The infalling material increased the density, and hence pressure (sim. is isothermal so they are directly proportional) at the sphere's outer edge. Since the sphere was a critical sphere, any increase in Pext(Rbe), sends the sphere out of equilibrium. Thus it seems a rise in thermal P alone (not strictly Ram presure) was sufficient in inducing collapse.
