F_{r} = -\frac{4ac}{3}\frac{T^3}{\kappa \rho}\frac{\D \ln T}{\D \ln \P} = \frac{4ac}{3}\frac{T^4}{\kappa \rho}\frac{\nabla}{\hp}.  \end{equation}  Finally the fictitious (but computable) radiative gradient can be defined as the gradient of temperature required by radiation to carry the total stellar flux:   \begin{equation} \begin{equation}\label{eq:totalflux}  F = F_{c} + F_{r} \equiv \frac{4ac}{3}\frac{T^4}{\kappa \rho}\frac{\nabla_r}{\hp}.  \end{equation}
