Stellar atmospheres
Abstract
The radiation field is considered along with the equation of transfer, the grey atmosphere, absorption crosssections, the equations of statistical equilibrium, and the solution of the transfer equation. A description of model atmospheres is presented, taking into account the classical modelatmospheres problem, Local Thermodynamic Equilibrium (LTE) radiativeequilibrium models, convection and models for latetype stars, the results of LTE modelatmosphere calculations for earlytype stars, nonLTE radiativeequilibrium models for earlytype stars, extended atmospheres, and semiempirical solar models. Attention is given to the line absorption profile, classical treatments of line transfer, nonLTE line transfer in the case of the twolevel atom and the multilevel atom, line formation with partial frequency redistribution, radiative transfer in moving atmospheres, the equations of hydrodynamics for an ideal compressible fluid, coronal winds, radiation hydrodynamics, and radiatively driven winds.
