Full non-LTE multi-level radiative transfer II. The case of a 5-level Ca ii atom with broadened excited levels
T. Lagache, M. Sampoorna, F. Paletou
The so-called full non-local thermodynamic equilibrium (FNLTE) radiative transfer problem allows us to take into account not only deviations of the radiation field from the Plancki…

Full non-LTE multi-level radiative transfer I. An atom with three bound infinitely sharp levels
Tristan Lagache, Frédéric Paletou, Malali Sampoorna
The standard nonlocal thermodynamic equilibrium (non-LTE) multi-level radiative transfer problem only takes into account the deviation of the radiation field and atomic populations…

Full non-LTE spectral line formation III. The case of a two-level atom with broadened upper level
M. Sampoorna, F. Paletou, V. Bommier +1
In the present paper we consider the full nonlocal thermodynamic equilibrium (non-LTE) radiation transfer problem. This formalism allows us to account for deviation from equilibriu…
