By introducing the non-dimensional variables defined by = (n + 1) (1 - θ) and ζ=|1+n|~(1/2)ξ,a generalized Lane-Emden equation of index n is obtained, which is applicable for any value of n (including the isothermal case), except in the case of constant pressure, n=-1.

From the study of the stability against the radial perturbations, a condition of instability is derived. With this criterion,...

By introducing the non-dimensional variables defined by = (n + 1) (1 - θ) and ζ=|1+n|~(1/2)ξ,a generalized Lane-Emden equation of index n is obtained, which is applicable for any value of n (including the isothermal case), except in the case of constant pressure, n=-1. The solutions are then discussed in terms of the characteris- tics of the singular points on the (u, v)-plane. From the study of the stability against the radial perturbations, a condition of instability is derived. With this criterion, we can transform the stability problem into a geometrical discussion. For Emden solu-tion, the whole range of n is divided into the stability region, the thermal and gravita-tional instability regions (fig. 5b).
