Objectives of the course :
The aim of this course is to study the stellar atmospheres by solving some models based on the solution of the equation of radiation transfer through different physical properties media .
Course Description:
This course contains the following subjects: Atomic structure, Deep study of the physical properties of the radiation field. Interaction of radiation with matter. Emission and absorption. The statistical equilibrium equation. The equation of radiation transfer and its solution for continuous radiation. The stellar Gray atmosphere.
