AGU 2019 SH001 Acceleration and Transport Processes of Energetic Electrons in Solar Flares and Interplanetary Space – abstract submission now open.

June 24, 2019, from Natasha Jeffrey

The abstract submission for the AGU Fall Meeting 2019 session SH001 — Acceleration and Transport Processes of Energetic Electrons in Solar Flares and Interplanetary Space is now open.

We welcome contributions from a broad range of topics that aim to address common challenges involved in understanding particle acceleration and transport at the Sun and in the heliosphere, from observations, theory and modelling.

Meeting date: AGU Fall Meeting 9-13 December 2019, San Francisco, CA.

Session organisers: Frederic Effenberger (Helmholtz Center, Potsdam), Sophie Musset (UMN), Nina Dresing (Kiel) & Natasha Jeffrey (U. of Glasgow).

ABSTRACT SUBMISSION DEADLINE: 31 July 2019 23:59 EDT/03:59 +1 GMT

Session abstract:
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.
