Session Abstract:
Magnetic Connectivity and Coronal Waves: From Chromosphere to Solar Wind
Abstract:
The solar corona is threaded with magnetohydrodynamic fluctuations propagating from the chromosphere to the heliosphere. Coronal wave phenomena, including EUV waves, Alfvénic fluctuations, shock fronts, and radio signatures, play roles in energy transport, particle acceleration, and solar-wind formation. Recent studies combining remote imaging and spectroscopy from SDO/AIA, IRIS, and Solar Orbiter (EUI, SPICE) with in-situ plasma and magnetic-field measurements from Parker Solar Probe (FIELDS, SWEAP) and Solar Orbiter (MAG, SWA), together with numerical modelling, have improved our ability to trace waves from the low corona into interplanetary space. Joint radio imaging from ground-based arrays such as LOFAR and spacecraft particle measurements show how shock-driven structures associated with coronal mass ejections accelerate energetic particles along open magnetic field lines, while detections of torsional Alfvénic motions using DKIST/Cryo-NIRSP support expectations for wave-mediated energy transport. Key challenges remain, including establishing robust magnetic connectivity between remote observations and in-situ sampling, quantifying wave evolution across the chromosphere–corona transition, and incorporating observational constraints into wave models. This session will bring together researchers working on remote sensing, in-situ measurements, and MHD modelling and connectivity frameworks to clarify the role of waves in heating the corona and establishing the solar-wind.
