    Convectively driven sinks and magnetic fields in the quiet Sun
    Solar surface convection displays highly localized sinks where cold plasma returns to the solar interior. On its way to being engulfed by a downdraft the plasma...

    Convectively driven vortex flows in the Sun
    We have discovered small whirlpools in the Sun, with a size similar to the terrestrial hurricanes (<0.5 Mm). The theory of solar convection predicts them, but...

    Detection of a Magnetic Discontinuity in the Upper Solar Chromosphere Associated with a Coronal Loop Brightening Observed by CLASP2.1
    We report the first detection of a magnetic discontinuity in the upper solar chromosphere associated with a coronal loop brightening. Our findings are based on...

    Determining the Magnetic Field in the Atmosphere of a Solar Active Region Observed by the CLASP2.1 Sounding Rocket Experiment
    We determine magnetic fields from the photosphere to the upper chromosphere combining data from the Hinode satellite and the CLASP2.1 sounding rocket experiment...

    Determining the Magnetic Field of Active Region Plages Using the Whole CLASP2/2.1 Spectral Window
    The Chromospheric LAyer SpectroPolarimeter missions, CLASP2 and CLASP2.1, demonstrated that the near-UV spectral region between 279.30 and 280.68 nm is suitable...

    Effects of Spectral Resolution on Simple Magnetic Field Diagnostics of the Mg II H and K Lines
    We study the effects of finite spectral resolution on the magnetic field values retrieved through the weak-field approximation (WFA) from the cores of the Mg II...

    Emergence of Internetwork Magnetic Fields through the Solar Atmosphere
    Internetwork (IN) magnetic fields are highly dynamic, short-lived magnetic structures that populate the interior of supergranular cells. Since they emerge all...
