	$0 = \frac{d^{2} x}{d r_{0}^{2}} + \frac{1}{r_{0}} [4 + \frac{d \ln P_{0}}{d \ln r_{0}}] \frac{d x}{d r_{0}} + [(3 - \frac{4}{γ_{g}}) \frac{d \ln P_{0}}{d \ln r_{0}}] \frac{x}{r_{0}^{2}} - \frac{1}{Δ} [\frac{d \ln P_{0}}{d \ln r_{0}} \cdot \frac{ρ_{c}}{ρ_{0}} (\frac{σ_{c}^{2}}{6 γ_{g}})] \frac{x}{r_{0}^{2}}$
where: $Δ \equiv \frac{M_{r}}{4 π r_{0}^{3} ρ_{0}},$ $σ_{c}^{2} \equiv \frac{3 ω^{2}}{2 π G ρ_{c}}$
