    The impact of surface dynamo magnetic fields on the solar iron abundance
    Most chemical abundance determinations ignore that the solar photosphere is significantly magnetized by the ubiquitous presence of a small-scale magnetic field...

    The influence of longitudinal density variation in coronal loops on the eigenfunctions of kink-oscillation overtones
    Context: As coronal loops are spatially at least partially resolved in the longitudinal direction, attempts have been made to use the longitudinal profiles of...

    The influence of the internal structuring of coronal loops on the properties of their damped transverse oscillations
    Context: The geometry and physical conditions in solar coronal loops are complicated and still not understood well. Recent high-resolution observations obtained...

    The integrated magnetic field of the Sun as seen by GOLF on board SOHO
    An objective of the GOLF experiment (Global Oscillations at Low Frequencies) on-board the SOHO (Solar and Heliospheric Observatory) space mission was to measure...

    The Intrinsic Dimensionality of Spectropolarimetric Data
    The amount of information available in spectropolarimetric data is estimated. To this end, the intrinsic dimensionality of the data is inferred with the aid of...

    The JCMT BISTRO Survey: A Spiral Magnetic Field in a Hub-filament Structure, Monoceros R2
    We present and analyze observations of polarized dust emission at 850 μm toward the central 1 × 1 pc hub-filament structure of Monoceros R2 (Mon R2). The data...

    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 canopy above light bridges
    An analysis of high-resolution Stokes observations of two light bridges in active region NOAA 8990 is presented. The observations were recorded with the La...
