Several methods, providing exact expressions for the radiation field in a semi-infinite atmosphere, are described in detail and applied to unpolarized and polarized continuous spectra and spectral lines. Among these methods, the Wiener?Hopf method, introduced in 1931 for a stellar atmospheric problem, is used today in fields such as solid mechanics, diffraction theory, or mathematical finance. Asymptotic analyses are carried out on unpolarized and polarized radiative transfer equations and on a discrete time random walk. Applicable when photons undergo a large number of scatterings, they provide criteria to distinguish between large-scale diffusive and non-diffusive behaviors, typical scales of variation of the radiation field, such as the thermalization length, and specific descriptions for regions close and far from boundaries. Its well organized synthetic view of exact and asymptotic methods of radiative transfer makes this book a valuable resource for both graduate students and professional scientists in astrophysics and beyond. 606 $aMathematical physics 606 $aAstrophysics 606 $aThermodynamics 606 $aHeat engineering 606 $aHeat$xTransmission 606 $aMass transfer 606 $aOptics 606 $aMathematical Methods in Physics 606 $aAstrophysics 606 $aEngineering Thermodynamics, Heat and Mass Transfer 606 $aLight-Matter Interaction 615 0$aMathematical physics. 615 0$aAstrophysics. 615 0$aThermodynamics. 615 0$aHeat engineering. 615 0$aHeat$xTransmission. 615 0$aMass transfer. 615 0$aOptics. 615 14$aMathematical Methods in Physics. 615 24$aAstrophysics. 615 24$aEngineering Thermodynamics, Heat and Mass Transfer. 615 24$aLight-Matter Interaction. 676 $a530.138 676 $a523.0192 700 $aFrisch$b H$g(He?le?ne),$01270982 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 912 $a9910574087803321 996 $aRadiative transfer$92994201 997 $aUNINA
