| | 3 | This pages describes the effects of placing a marginally stable Bonnor Ebert sphere in different ambient mediums. Two ambient mediums and their effects on BE spheres were measured - a) a uniform light ambient medium (rho=rho(Rbe)/100), and b) an ambient medium with density that matches the density at the sphere's outer edge (rho=rho(Rbe)). The aim was to see if the effect of the "matched" ambient was induced collapse of the sphere, triggered by the ram pressure of the infalling ambient material gravitationally accelerated by the BE sphere. The ram pressure was calculated at the sphere's outer edge and indeed exceeded the critical threshold of external pressure on the BE sphere, resulting in collapse. The sphere in the light ambient medium, however, remained dynamically stable, oscillating slowly about its equilibrium values for ~ 5 crossing times. |
