    Solar oscillations as seen in the NaI and KI absorption lines
    Data on the solar p modes observed simultaneously in the solar NaI and KI absorption lines were obtained in 1985 by operating two independent resonant...

    Spectroscopic determination of intensities of umbral bright features and adjacent background
    Profiles of the Na I D doublet in three bright features (clusters of umbral dots), located in a relatively dark umbra, were analyzed by means of the 'local two...

    The continuum intensity-magnetic field relation in sunspot umbrae
    We describe the work carried out to obtain observational evidence of a local relation between the temperature and the magnetic field in different regions of...

    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 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...
