Introduction
Bonnor-Ebert Sphere
This information extracted from an accompanying chapter on the Bonnor-Ebert sphere. Ebert (1955) and Bonnor (1956) are credited with constructing the first such models and, most significantly, discovering that, for any specified sound speed and applied external pressure, there is a mass above which no equilibrium configuration exists.
