Recall, how this radiative energy ''couples'' to the gas is given by the coupling term in the radiation equation, not shown here. 59 60 == Estimating the diffusion time == 61 62 Estimating [[latex($\lambda$)]]... 63 64 65 Depending on the value of R, we will get different values of [[latex($\lambda$)]]. So, we start by approximating R. 66 67 Note that 68 69 [[latex($\frac{\nabla E}{E}=\frac{d(\ln E}{E}$)]]
