A new analytic approximation to the isothermal, self-gravitating sphere
We derive a new analytic prescription for the density of the non-singular, isothermal, self-gravitating sphere. The proposed prescription gives the density stratification for all radii with a maximum error of ≈1%. This is an improvement over previous prescriptions, which only gave such an accuracy over limited radial domains.
