Particles in a Static, Spherical Geometry | PlainTex, 12pages | null | null | IP-ASTP-19-93 | hep-ph astro-ph gr-qc | null | The asymptotic form of the energy density for a gas of particles surrounding
a sphere of mass $M$ and radius $R$ is studied using Einstein's equations. It
is shown that if the pressure of the gas $p$ varies linearly with the energy
density $\rho$ for small $\rho$, then $\rho\sim 1/r^2$ for large $r$.
