Variants of the equation assume equilibrium (no change over time), an approximation of the composite of all Wavelengths (Gray Atmosphere, using the Rosseland Mean Opacity), a directional component (Eddington Approximation) and/or that variation in the medium is in a single direction (Plane-parallel Atmosphere). These are used in models of Stellar Structure. equation,physics,EMR)http://www.met.reading.ac.uk/~ross/Science/RadTrans.pdf Referenced by:
