Energy Balance
Coupling between thermal conduction and radiative transfer
kT=kf+kes
kf, kp, kj = flux, planck and
absorption mean opacities
kes = 0.2(1+X) =
scattering opacity
X = hydrogen fraction
Thermal conductivity
Boundary conditions:
Energy-averaged
and angle-averaged depression
factor for the surface
emissivity (computed
numerically as before)
