Astrophysical: Radiative transfer

  • Publication
    Formation of polarized spectral lines in atmospheres with horizontal inhomogeneities
    We study the problem of the generation and transfer of spectral line intensity and polarization in models of stellar atmospheres with horizontal plasma...

    Full Stokes-vector Inversion of the Solar Mg II h and k Lines
    The polarization of the Mg II h and k resonance lines is the result of the joint action of scattering processes and the magnetic field–induced Hanle, Zeeman...

    G5T: ExoMolHD: Precision spectroscopic data for studies of exoplanets and other hot atmospheres
    The ExoMol project ( www.exomol.com) provides comprehensive spectroscopic data (line lists) for the study of atmospheres of exoplanets and other hot bodies...

    Galactic wind X-ray heating of the intergalactic medium during the Epoch of Reionization
    The diffuse soft X-ray emissivity from galactic winds is computed during the Epoch of Reionization (EoR). We consider two analytic models, a pressure-driven...

    Gauss-Seidel and Successive Overrelaxation Methods for Radiative Transfer with Partial Frequency Redistribution
    The linearly polarized solar limb spectrum that is produced by scattering processes contains a wealth of information on the physical conditions and magnetic...

    Height Variation of the Vector Magnetic Field in Solar Spicules
    Proving the magnetic configuration of solar spicules has hitherto been difficult due to the lack of spatial resolution and image stability during off-limb...

    Herschel-ATLAS: The dust energy balance in the edge-on spiral galaxy UGC 4754
    We use Herschel PACS and SPIRE observations of the edge-on spiral galaxy UGC 4754, taken as part of the H-ATLAS SDP observations, to investigate the dust energy...

    Hubble constant and nuclear equation of state from kilonova spectro-photometric light curves
    The merger of two compact objects of which at least one is a neutron star is signalled by transient electromagnetic emission in a kilonova (KN). This event is...

    IAU G5 Talk: Winds of Magnetic Massive Stars
    Massive stars (at least eight times as massive as the Sun) possess strong stellar winds driven by radiation. With the advent of the so called MiMeS...
