Abstract:
A concise description of the method of obtaining the solution of radiative trans-
fer equation which can be applied to di®erent geometrical and physical systems is given.
This paper mainly deals with the steps for obtaining solution of transfer equation like (1)
interaction principle for di®erent geometries, (2) star product and (3) calculation of radiation
field at internal points, and their applications in stellar atmosphere problems; in particular
(a) study of re°ection e®ect in close binary systems and (b) stellar winds in O and B type
stars are discussed with their results.
