The study of the radiative transfer problem is crucial for the characterisation of circumstellar environments. Radiative processes play a major role in the determination of physical observables of these astrophysical objects, such as the temperature, abundances, velocity fields, etc. The description of the frequency dependent and...

Context. The study of the continuum radiative transfer problem inside circumstellar envelopes is both a theoretical and numerical challenge, especially in the frequency-dependent and multi-dimensional case. While approximate methods are easier to handle numerically, they often fail to accurately describe the radiation field inside complex...
