RAGA, A. C. et al. A new analytic approximation to the isothermal, self-gravitating sphere. Rev. mex. astron. astrofis [online]. 2013, vol.49, n.1, pp.63-69. ISSN 0185-1101.

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.

Keywords : galaxies [halos]; ISM [clouds]; stars [formation].
