    Polarized resonance line transfer in a spherically symmetric medium with angle-dependent partial frequency redistribution
    In a stellar atmosphere, the resonance line polarization arises from scattering of limb-darkened radiation field by atoms. This spectral line polarization gets...

    PORTA: A three-dimensional multilevel radiative transfer code for modeling the intensity and polarization of spectral lines with massively parallel computers
    The interpretation of the intensity and polarization of the spectral line radiation produced in the atmosphere of the Sun and of other stars requires solving a...

    Probing 3D and NLTE models using APOGEE observations of globular cluster stars
    Context. Hydrodynamical (or 3D) and non-local thermodynamic equilibrium (NLTE) effects are known to affect abundance analyses. However, there are very few...

    Probing downflows in solar magnetic elements: the Fe II test
    In an attempt to assess the physical realism of the plage flux tube model derived by Bellot Rubio, Ruiz Cobo & Collados (cite{brc}, cite{bellot}) we extend its...

    Probing photoionization models in two well-studied extended emission-line regions - Centaurus A and 3C 227
    The observed emission-line ratios of the extended emission-line regions of Cen A and 3C 227 are compared with the theoretical results from photoionization...

    Probing the {Na} BT I D and {K} BT I lambda 7699 resonance lines sensitivity to background opacity in late-type stars
    We have measured the equivalent width WK of the K i resonance line at 7699 Angstroms for a large sample of low activity late-type stars observed with high...

    Radiation-hydrodynamical model atmospheres across the Hertzsprung-Russell diagram
    In the EU funded Marie Curie Excellence Team CIFIST (Cosmological Impact of the FIrst STars) work is under way to construct 3D radiation-hydrodynamical model...
