    Observation and Modeling of Anomalous CN Polarization Profiles Produced by the Molecular Paschen-Back Effect in Sunspots
    We report novel spectropolarimetric observations of sunspots carried out with the Tenerife Infrared Polarimeter in a near-IR spectral region around 15410 Å...

    Observation of Convective Collapse and Upward-moving Shocks in the Quiet Sun
    We present spectropolarimetric evidence of convective collapse and destruction of magnetic flux by upward-moving fronts in the quiet Sun. The observational...

    Observational and numerical characterization of a recurrent arc-shaped front propagating along a coronal fan
    Context. Recurrent, arc-shaped intensity disturbances were detected by extreme-ultraviolet channels in an active region. The fronts were observed to propagate...

    Observational Evidence for Small-Scale Mixture of Weak and Strong Fields in the Quiet Sun
    Three different maps of the quiet Sun, observed with the Advanced Stokes Polarimeter (ASP) and the Diffraction-Limited Stokes Polarimeter (DLSP), show evidence...

    Observational signatures of the simulated solar photosphere
    Most of the visible light coming from the Sun originates in the solar photosphere. Numerical simulations are a common tool to study the solar atmosphere...
