Abstract:
In this work we consider the numerical solution of a radiative transfer
equation for modeling the emission of photons in stellar atmospheres.
Mathematically, the problem is formulated in terms of a weakly singular
Fredholm integral equation defined on a Banach space. Computational
approaches to solve the problem are discussed, using direct and iterative strategies that are implemented in open source packages.
