Discontinuous Galerkin finite element method for the continuum radiative transfer problem inside axis-symmetric circumstellar envelopes
J. Perdigon, M. Faurobert, G. Niccolini
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-…

New boundary conditions for the approximate flux-limited diffusion radiative transfer in circumstellar environments: test case study for spherically symmetric envelopes
Jérémy Perdigon, Gilles Niccolini, Marianne Faurobert
In order to constrain the models describing circumstellar environments, it is necessary to solve the radiative transfer equation in the presence of absorption and scattering, coupl…
