Hi Fred,

The density of a gaseous mass in a state of 'hydrostatic
equilibrium' (i.e. the pressure gradient force exactly cancelling the
gravitational force) is proportional to 1/r^2 (see section b) of my
pagehttp://www.plasmaphysics.org.uk/research/starformation.htm,where
I have shown this in connection with the star formation problem).

Thomas,
Your Equation (8) assumes an isothermal, ideal gas. Such is almost
NEVER the case. In gas clouds there are spatial variations in
temperature. Planets and stars are condensed phases where the
compressibility never follows the gas laws. Start with a more
realistic equation of state:
