The 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 by: 8. This book is a classic. Any astronomer working on stellar atmospheres or stellar spectra needs to have this book in his or her library. The sections on radiative transfer is excellent. However, I personnaly prefer the first edition of this book because the explanations and the derivations are clearer in that version.5/5(5). Stellar Atmospheres. This book covers the following topics: Definitions of and Relations between Quantities used in Radiation Theory, Blackbody Radiation, The Exponential Integral Function, Flux, Specific Intensity and other Astrophysical Terms, Absorption, Scattering, Extinction and the Equation of Transfer, Limb Darkening, Atomic Spectroscopy, Boltzmann's and Saha's Equations, Oscillator.

To make the modelling of stellar atmospheres manageable, a variety of assumptions are traditionally made about stellar photospheres: (1) plane-parallel vs. spherical geometry (2) homogeneity (3) stationarity (4) hydrostatic equilibrium (5) flux constancy (radiative equilibrium) (6) local thermodynamic Size: 1MB.

The stellar atmosphere is divided into several regions of distinct character: The photosphere, which is the atmosphere's lowest and coolest layer, is normally its only visible part.  Light escaping from the surface of the star stems from this region and passes through the higher layers.
