Diffusion time estimate

Starting from:

We get:

L is the size of our system, c is speed of light, kappa_R is the rosseland specific mean opacity, rho is density of the system, and lamba is a dimensional parameter that has to do with gradient length scales of the radiative energy.

Offner et al '09 gives,

for T=10 K gas.
