Schuster-Schwarzschild model

(approximation of a star's internal EMR's divergence from isotropic)

The Schuster-Schwarzschild model is an approximation of electromagnetic radiation (EMR) intensity as a function of direction, i.e., a description of how intense the light is when viewed in different directions, for example, within an atmosphere. It is a simplification of reality that makes calculations of radiative transfer and absorption lines tractable.

It is an example of a two-stream approximation which model EMR intensity differences in terms of upward versus downward. In this model, all directions below horizontal have a single constant intensity and all those above horizontal have another.
