Abstract
In this paper the effect of collisions and photo-ionizations on monochromatic radiative equilibrium is considered. A formalism is developed which includes the theory of stellar absorption lines (Strömgren) and the theory of nebular luminosity (Zanstra) as two limiting cases. A second approximation for the nebular problem is also sketched. The mathematical analysis is devoted to the treatment of the three-state problem including collisions. When collisions can be neglected, the approximate equations of transfer used admit of two flux integrals and two K-integrals.
