    Channeling 5 Minute Photospheric Oscillations into the Solar Outer Atmosphere through Small-Scale Vertical Magnetic Flux Tubes
    We report two-dimensional MHD simulations which demonstrate that photospheric 5 minute oscillations can leak into the chromosphere inside small-scale vertical...

    Chromospheric polarimetry through multiline observations of the 850-nm spectral region - II. A magnetic flux tube scenario
    In this publication, we continue the work started in Quintero Noda et al., examining this time a numerical simulation of a magnetic flux tube concentration. Our...

    Chromospheric polarity reversals on sunspots. Are they consistent with weak line emission?
    Photospheric and chromospheric solar magnetograms sometimes show opposite polarity. This intriguing phenomenon is associated with the emergence of magnetic flux...

    Chromospheric reversals in the emergence of an ephemeral region
    Context: The behaviour of both ephemeral regions and moving magnetic features has been often described for the photospheric layer, but not for the chromosphere...

    CLASP Constraints on the Magnetization and Geometrical Complexity of the Chromosphere-Corona Transition Region
    The Chromospheric Lyman-Alpha Spectro-Polarimeter (CLASP) is a suborbital rocket experiment that on 2015 September 3 measured the linear polarization produced...
