    High-resolution imaging and near-infrared spectroscopy of penumbral decay
    Aims: Combining high-resolution spectropolarimetric and imaging data is key to understanding the decay process of sunspots as it allows us to scrutinize the...
  • Publication
    High-resolution observations of recurrent jets from an arch filament system
    Context. Solar jets are collimated plasma ejections along magnetic field lines observed in hot (extreme-ultraviolet (EUV) jets) and cool (chromospheric surges)...

    High-Resolution Proper Motions in a Sunspot Penumbra
    Local correlation tracking techniques are used to measure proper motions in a series of high angular resolution (~0.1") penumbra images. If these motions trace...

    Horizontal flow fields in and around a small active region. The transition period between flux emergence and decay
    Context. The solar magnetic field is responsible for all aspects of solar activity. Thus, emergence of magnetic flux at the surface is the first manifestation...
