Exploring multi-scale magnetic flux ropes in space plasmas
Convener: Ranadeep SarkarECSECS | Co-conveners: Simon Good, Eleanna AsvestariECSECS, Emilia Kilpua, Emiliya Yordanova
The heliosphere is an expansive domain for the study of fundamental plasma phenomena. Magnetic flux ropes (MFRs), characterized by their twisted magnetic field lines, are ubiquitous in space plasmas and play a pivotal role in shaping solar, interplanetary, and planetary magnetospheric dynamics. On a larger scale, MFRs can take the form of coronal mass ejections (CMEs) and propagate through the heliosphere, causing space weather phenomena. On a smaller scale, MFRs can dynamically form as plasmoids along current sheets at flaring reconnection sites, within the heliospheric current sheet and planetary magnetotails, and they can arise naturally from turbulence. They can also be found inside magnetosheaths preceding CMEs and planetary magnetopauses. In addition, MFRs may intricately weave within the solar atmosphere, manifesting as mesoscale structures such as filament channels, sigmoids, or coronal cavities.

This session seeks to bring together experts, researchers, and enthusiasts from diverse disciplines to foster a comprehensive understanding of magnetic flux ropes using both observational and modelling efforts across various scales — ranging from the structures at the smallest plasma length scales to the largest, heliospheric-scale phenomena. We encourage submissions on new advancements in developing tools to extract information on MFR occurrence, twist, structure, and temporal evolution from observational, theoretical, and simulation data, and submissions on the relation of MFRs to fundamental plasma processes. Additionally, we invite submissions that focus on the advancement of flux-rope models and their integration into analytical and MHD-based space weather forecasting tools. Contributions from observational studies that utilize multi-wavelength/multi-spacecraft remote-sensing or in situ data to address the outstanding questions about MFRs are also welcome.
