+Starting with a set parameter space of peak temperatures [T<sub>9</sub> = 4 - 7] and densities [$\rho$ = 10<sup>5</sup> - 10<sup>7</sup> g/cm<sup>3</sup>].
+We use analytic adiabatic freeze-out trajectories (Hoyle et al. 1964; Fowler & Hoyle 1964) which satisfy the differential equations:
+\begin{equation}
+\frac{dT}{dt} = \frac{-T}{3\tau} \hspace{1cm} \frac{d\rho}{dt} = -\frac{\rho}{\tau}
+\end{equation}
+Where $\tau$ is some static free-fall timescale.
+This **obviously** leads to:
+\begin{equation}
+T(t) = T_0 exp(-t/3\tau) \hspace{1cm} \rho (t) = \rho_0 exp(-t/\tau)
+\end{equation}
+where $T_0$ and $\rho_0$ are the peak temperature and density in the supernova.
+Then you run the code, and it doesn't work.
