  • Summary

    The main mode of energy transport through the photosphere is via radiation, i.e., photons.We consider how these photons are created and destroyed and how the energy flows outward.We build on the material from the previous two chapters and formulate the mathematical integral needed to calculate the spectrum of a star.Convection is considered briefly, mainly because it introduces velocity fields into the photosphere.
