    Non-local thermodynamic equilibrium inversions from a 3D magnetohydrodynamic chromospheric model
    Context. The structure of the solar chromosphere is believed to be governed by magnetic fields, even in quiet-Sun regions that have a relatively weak...

    Non-local thermodynamic equilibrium inversions of the Si I 10827 Å spectral line
    Inferring the coupling of different atmospheric layers requires observing spectral lines sensitive to the atmospheric parameters, particularly the magnetic...

    Non-LTE abundance corrections for late-type stars from 2000 Å to 3 µm. I. Na, Mg, and Al
    Context. It is well known that cool star atmospheres depart from local thermodynamic equilibrium (LTE). Making an accurate abundance determination requires...
