Session IUGG sur les ondes de choc

Annonce transmise par Alexis Rouillard (IRAP)

Je souhaiterais à nouveau attirer votre attention sur une série de sessions de l'IUGG 2023 intéressantes pour la communauté PNST. Les 25 sessions, allant de A01 à A25, couvrent une variété de sujets dont l'aéronomie, la magnétosphère, le vent solaire, les éruptions solaires, etc. Ces sessions peuvent être consultées à l'adresse suivante : https://www.iugg2023berlin.org/899-2/

IUGG, l'assemblée générale de l'Union internationale de géodésie et de géophysique en 2023, se tiendra au CityCube de Berlin du 11 au 20 juillet 2023. La date limite pour la soumission des résumés  est le 14 février 2023.

Vous trouverez ci-dessous des informations sur la session A17 :

A17 Interplanetary Shocks, Particle Acceleration, and Transport in Solar and Heliospheric Physics

Convener(s): Manolis Georgoulis (Greece)

Co-Convener(s): Alexis Roulliard (France) Camilla Scolini (USA ) Robert Wimmer-Schweingruber (Germany) Alessandro Bemporad (Italy)

Description
Collisionless shock waves produced by coronal mass ejections and corotating interaction regions are known to accelerate energetic particles. The enhancements in energetic particle fluxes at Earth can pose a hazard to humans and technology in space and at high altitudes. The mechanisms that accelerate particles in shock waves are still debated and include, for instance, shock-drift, diffusive shock, and betatron acceleration. The shock geometry and strength and the presence of pre-energized seed particle populations are also thought to significantly affect the capacity of shock waves to accelerate particles. The advent of Solar Orbiter and Parker Solar Probe has opened a new era in this branch of high-energy solar physics by allowing detailed measurements of Solar Energetic Particles (SEPs) closer to the Sun, thereby alleviating some challenges by allowing more in-depth studies of the relative effects of acceleration and transport processes on SEP events. This session addresses the acceleration and transport of energetic particles at shock waves by inviting research contributions focused on the analysis of particles measurements in the inner heliosphere by the current fleet of operating spacecraft as well as through theoretical studies including numerical simulations.
