Astrophysicists have developed several very different methodologies for solving the radiative transfer equation. Accurate methods, fast methods, probabilistic methods and approximate methods are all explained, including the latest and most advanced techniques. The book includes the different methods used for computing line profiles, polarization due to resonance line scattering, polarization in magnetic media and similar phenomena. Exercises at the end of each chapter enable these methods to be put into practice, and enhance understanding of the subject.

Oxford, Clarendon Press, 1950, 405 pp. The problem of specifying the radiation field in an atmosphere which scatters light in accordance with well-defined physical laws originated in Lord Rayleigh's investigations in 1871 on the illumination and polarization of the sunlit sky. But the fundamental equations governing Rayleigh's particular problem had to wait seventy-five years for their formulation and solution. However, the subject was given a fr...

In nuclear technology one has been dealing with the analogous equations of neutron transport. In recent years, applications of radiative transfer in combustion machine design and in medicine became more and more important. In each discipline various codes have been developed that—al...

Pergamon Press, Oxford, New York, 1973, 298 pp At higher temperatures (say, millions of degrees Kelvin), the energy and momentum densities of the radiation field may become comparable to or even dominate the corresponding fluid quantities. In this case, the radiation field significantly affects the dynamics of the fluid. Hydrodynamics with explicit account of the radiation energy and momentum contributions constitutes the charter of "radiation hy...

The areas of most importance in this respect are plasma physics, radiative transfer, rarefied gas dynamics and neutron transport theory. Whilst neutron transport clearly deals with neutral particles, plasma physics and some aspe...

Often one can easily comprehend seemingly complex phenomena by investigating each of the basic processes. For example, the properties of a gas or liquid result from the interactions of the molecules which constitute the fluid, as described in molecular gas dynamics.
