Acceleration and Transport Processes of Energetic Electrons in Solar Flares and Interplanetary Space

Session ID#: 72623

Session Description:
The relation between energetic particle populations accelerated at the Sun, as seen in radiative signatures, and particles measured in-situ, is a fundamental subject in Heliophysics. Observations during the RHESSI era demonstrated the still poorly understood existence of a connection between solar flare signatures of accelerated electrons at the Sun and the corresponding solar energetic particles detected at 1AU. A key question is thus: Can these distinctly observed electron populations originate from the same flare-acceleration region? Different acceleration and transport processes in the solar atmosphere and in interplanetary space can contribute to the observed non-thermal temporal, spatial, and spectral particle signatures. We encourage contributions from observational, theoretical and simulation studies addressing this topic. Cross-community, joined efforts hold the potential to lead to a greater understanding of the important physical processes involved in electron acceleration and will enable new approaches to interpret the near-Sun observations from Parker Solar Probe and Solar Orbiter.
