Some estimates of the radiative Rosseland mean opacity
Journal of Quantitative Spectroscopy and Radiative Transfer, 1967Abstract The effect of atomic number Z on the Rosseland mean opacity is presented in graphic form for a large range of temperatures and densities. This permits a rapid determination of the dominant process and, in many cases, greatly simplifies the calculation of a good approximation of the Rosseland mean opacity.

On the definition and use of grey opacities in radiative transfer problems
Transport Theory and Statistical Physics, 1971Abstract The general problem of reducing a frequency-dependent radiative transfer problem to an equivalent grey problem is discussed. In particular, we construct, from the integral transport equation, an asymptotic solution to be used in forming grey opacities.
