F.10 hernquist

potname=hernquist potpars= $\Omega,M,r_c$

Potential is given by: $\begin{displaymath} \Phi = - { M \over {(r_c+r)}} \end{displaymath}$ and mass $\begin{displaymath} M(r) = M { r^2 \over {(r+r_c)}^2 } \end{displaymath}$ and density $\begin{displaymath} \rho = { M \over {2\pi}} {r_c \over r} { 1 \over {(r+r_c)}^3} \end{displaymath}$
