Abstract

Isothermal spheres and charged dust

Author(s): Gerald E.Marsh

The density profiles of dark matter halos are often modeled by an approximate solution to the isothermal Lane-Emden equation with suitable boundary conditions at the origin. It is shown here that such a model corresponds to an exact solution of the Einstein-Maxwell equations for charged dust.
