Opis

Astrophysicists have developed several very different methodologies for solving the radiative transfer equation. An Introduction to Radiative Transfer applies these techniques to stellar atmospheres, planetary nebulae, supernovae, and other objects with similar geometrical and physical conditions. Accurate methods, fast methods, probabilistic methods and approximate methods are all explained, including the latest and most advanced techniques. The book includes the different techniques used for computing line profiles, polarization due to resonance line scattering, polarization in magnetic media and similar phenomena.
