Polytropic solutions. Top: density profiles solutions to the Lane-Emden equation with different polytropic indexes n. Bottom: total enthalpy per unit mass compared to gravitational interaction energy per unit mass assuming either a homogeneous density profile or accounting for inhomogeneities. Blue and green crosses are indistinguishable.
