WebTo interpret a stellar spectrum quantitatively, knowledge of the variation in temperature and density with depth in the star’s atmosphere is needed. Some general theoretical … WebThe book is ideal for astronomers who want to acquire deeper insight into the physical foundations of the theory of stellar atmospheres, or who want to learn about modern computational techniques for treating radiative transfer in non-equilibrium situations. It can also serve as a rigorous yet accessible introduction to the discipline for ...
