    The Impact of Angle-dependent Partial Frequency Redistribution on the Scattering Polarization of the Solar Na I D Lines
    The long-standing paradox of the linear polarization signal of the Na I D 1 line was recently resolved by accounting for the atom's hyperfine structure and the...

    The loopy Sun: resolving the small-scale solar magnetism
    Solar magnetism may look deceptively boring (a rather common star with relatively low activity). As it turns out, even the most quiet areas of the Sun (away...

    The Polarization of the Solar Ba II D<SUB>1</SUB> Line with Partial Frequency Redistribution and Its Magnetic Sensitivity
    We investigate the main physical mechanisms that shape the intensity and polarization of the Ba II D 1 line at 4934 Å via radiative transfer numerical...

    The wounded Sun
    The Sun is a magnetic star, not as magnetic as some stars, or as it was when itwas younger, but nonetheless magnetic fields dominate and even construct...
