    The coronal heating problem: why MHD waves are trendy
    The coronal heating problem has been with us for almost 70 years now. Among the different proposed explanations, wave-based heating mechanisms are recurrently...

    The COSMO Chromosphere and Prominence Magnetometer
    The Chromosphere and Prominence Magnetometer (ChroMag) is a synoptic instrument with the goal of quantifying the intertwined dynamics and magnetism of the solar...

    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 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 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 search for solar oscillations, 1974 to 1976
    Using a resonant scattering spectrometer, observations of integral solar light have been recorded and analyzed to determine the existence of solar oscillations...

    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...
