    Testing new ideas of sunspot formation: the negative effective magnetic pressure instability
    The formation of active regions and its most visible outcome-sunspots-are still a matter of research. Magnetic flux tubes theory tends to explain the formation...

    The Impact of Limited Time Resolution on the Forward-scattering Polarization in the Solar Sr I 4607 Å Line
    Theoretical investigations predicted that high spatiotemporal resolution observations in the Sr I 4607 Å line must show a conspicuous scattering polarization...

    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 Magnetic Nature of Our Sun
    This talk will give an overview of our understanding of the Sun in the 1960's, the major discoveries since then, and the main questions that need to be answered...

    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...
