    Inversion of Stokes profiles
    An inversion code of Stokes line profiles is presented. It allows the recovery of the stratification of the temperature, the magnetic field vector, and the line...

    Inversion of Stokes Profiles from Solar Magnetic Elements
    We describe a new LTE inversion code for the analysis of Stokes profiles emerging from unresolved magnetic elements. It has been specifically designed to obtain...

    Isotropic inelastic and superelastic collisional rates in a multiterm atom
    The spectral line polarization of the radiation emerging from a magnetized astrophysical plasma depends on the state of the atoms within the medium, whose...

    Isotropic Inelastic Collisions in a Multiterm Atom with Hyperfine Structure
    A correct modeling of the scattering polarization profiles observed in some spectral lines of diagnostic interest, the sodium doublet being one of the most...

    Iteration Profiles in Radiative Transfer Problems. I. From Vectorial to Scalar Coupling
    We have recently introduced a new algorithm, the implicit integral method (IIM), for solving radiative transfer problems in which the specific source functions...

    Iterative Methods for the Non-LTE Transfer of Polarized Radiation: Resonance Line Polarization in One-dimensional Atmospheres
    This paper shows how to generalize to non-LTE polarization transfer some operator splitting methods that were originally developed for solving unpolarized...

    JO PULS: “One of the current prime challenges is the evolution of massive binaries”
    His interest about the radiative transfer began in a lecture about "Stellar Atmospheres" he attended when he was studying his Physics degree. He was previously...

    Lagrangian and Eulerian Stratifications of Acoustic Oscillations through the Solar Photosphere
    We evaluate the stratification of acoustic oscillations in the solar photosphere in both the Lagrangian (comoving) frame of reference and the Eulerian (inertial...

    Line Asymmetries and the Microstructure of Photospheric Magnetic Fields
    A systematic structuring of magnetic fields over scales much smaller than the mean free path of photospheric photons may be responsible for the observed...
