     175[[latex($\boxed{l=\frac{1}{\kappa_R\rho}}$)]]
     176
     177and
     178
    175179[[latex($\boxed{1 M_\odot =\rho l^3}$)]]
    176180
    177 Solving these two equations gives:
    178 
    179 [[latex($h=$)]]
    180 
    181 [[latex($l=$)]]
    182 
     181Solving these equations equations gives:
     182
     183[[latex($h=l=.0068 ~pc$)]]
     184
     185''' So a (uniform density) core that contains a solar mass, has to be .0068 to be optically thick. That is an interesting result. '''

     187Recalculating the sims parameters, and diffusion time, gives:
     188
     189|| [[latex($\lambda$)]] || .3 ||
     190|| l = h = r (box radius)|| .0068 (pc) =  2.1e+16 (cm)||
     191|| [[latex($\rho$)]] || 2.69*10^-17^ (g cm^-3^) ||
     192|| [[latex($\kappa_R$)]] || 2.3 (cm^2^ g^-1^) ||

     195[[latex($t_{diff}\approx \frac{L^2}{c}\frac{\kappa_R \rho}{\lambda}$)]]
