| Popis: | This paper contains a review of methods for solving line transport problems in moving media in terms of the symmetric/antisymmetric radiation-field averages introduced by P. Feautrier. These techniques have proven to be popular and effective in a wide range of astrophysical applications, and may be useful in other areas of computational physics. We outline the physical motivation, formulation, and algorithms for both observer-frame and comoving-frame methods, each of which has distinctive advantages and disadvantages. We cite basic references to provide easy access to the astrophysical literature for workers in other fields. |
