Symposium title: “A28 Turbulent energy dissipation and particle dynamics in the solar wind and the solar corona”
Convener(s): Luca Franci (Northumbria University, UK, luca.franci@northumbria.ac.uk)

Description: Turbulence is a ubiquitous and fundamental ingredient in the dynamics of space and astrophysical plasmas. It induces a transfer of energy from macroscopic fluid scales down to sub-electron scales, thus contributing to energy dissipation and to particle heating and acceleration, all processes of great interest for the astrophysical community. Our understanding of the different phenomena at play in turbulent plasmas keeps improving at a fast pace, thanks to new ground-breaking observations by spacecraft such as Solar Orbiter and Parker Solar Probe in the solar wind and, more recently, even in the solar corona, combined with theoretical models and advanced numerical simulations. This session aims at reflecting all aspects of the current research on plasma turbulence and its effects in the solar wind and in the solar corona. It will address different properties of turbulence (e.g., spectral properties, cross-scale energy transfer, intermittency), its development and evolution, its interaction with other processes (e.g., magnetic reconnection, instabilities, wave-particle interactions) and with the solar wind expansion, and its key role for energy dissipation and the particle dynamics. We welcome contributions from theory, simulations, and observations focusing on this plurality of aspects. This time, special consideration will be given to studies in preparation for future observations by upcoming space missions (e.g., Interstellar and Acceleration Mapping and HelioSwarm) and candidate missions (e.g., Plasma Observatory).

As the Sun approaches the maximum of Solar Cycle 25 there is growing interest in when the cycle will peak and how active the Sun will be when it does. This Discussion Meeting will focus on the solar activity cycle, the dynamo processes that drive it, its interaction with helioseismic diagnostics, our ability to predict how future cycles will evolve and the implications of observations of the current solar cycle for our understanding of previous cycles. We will also consider the consequences of varying activity cycles on orbiting planets, including Earth. There are still many unresolved questions about the Sun’s dynamo, and this meeting will facilitate discussion between those modelling the dynamo and those whose focus is on observing the Sun’s interior, its atmosphere, and the Sun-Earth environment, all of which have features that must be accounted for by such models. This session will be of interest to both the Solar Physics and MIST communities. We will especially welcome contributions from helioseismologists, dynamo modellers and those interested in the long-term evolution of the solar magnetic activity cycles.

The day will also include an informal discussion session on needs and prospects for future solar observatories, both space- and ground-based.

Please submit abstracts here: https://docs.google.com/forms/d/e/1FAIpQLScQbt1Pvn7IgiIzsGg173csejbxmCj1gVPUwME2MGhxcJZqaA/viewform by 16th December.

We would like to draw your attention to the ST17 session: ‘Advances in Our Understanding of Plasma Flows and Waves in the Solar Atmosphere from Single, Multi-fluid, and Kinetic Model Perspectives’ in the framework of the Asia Oceania Geosciences Society (AOGS) conference.

The 22nd Annual Meeting of the Asia Oceania Geosciences Society is taking place from 27 July to 1 August 2025 in Marina Bay Sands, Singapore. Further details regarding abstract submission, registration, accommodation and relevant deadlines can be found on the meeting website: https://www.asiaoceania.org/aogs2025/public.asp?page=home.asp

Abstract Submission Deadline: 18 Feb 2025

Conveners:
Dr Malcolm Druett (The University of Sheffield, United Kingdom), Prof Viktor Fedun (The University of Sheffield, United Kingdom), Dr Wenzhi Ruan (Max Planck Institute for Solar System Research, Göttingen, Germany), Dr Sergiy Shelyag (Flinders University, Australia), Dr Abhishek Srivastava (Indian Institute of Technology (BHU) Varanasi, India)

Session Description
Modern high spatial and temporal resolution numerical and observational studies of dynamical solar processes e.g. flares, CMEs, vortices, and jets provide us with unprecedented possibilities to understand various plasma-waves and flow-related physical processes in the solar atmosphere and beyond. The development of theoretical models of the solar environment is essential to represent the complex interactions between magnetic fields, plasma flows and waves. In quiet-Sun and active regions, this interplay can result in turbulence generation, solar flares, vortex motion formation, plasma jet propulsion, and the beginning of instabilities. The combination of data from modern space and ground-based solar instruments, e.g., Parker Solar Probe, Solar Orbiter, Aditya-L1, IRIS, CHASE, COSMO, DKIST, DST, BBSO and SST with the simulation capabilities of codes such as ARMS, Bifrost, CO5BOLD, MURaM, MPI-AMRVAC, SAC, Ramen, and R2D2 empower us to interpret, theorise, forecast behaviours, as well as provide requirements for the design of future instrumentation and codes to be capable of answering scientific questions related to our understanding of coronal heating, the origin of supersonic wind, solar activity, and further concatenating to space weather. In the framework of the proposed session, we will be focussing on (1) energy transport mechanisms within solar flares; (2) the role of non-thermal particles; (3) plasma vortical structures and how they support wave propagation and energy supply to the upper layers of the solar atmosphere; (4) multi-scale (non-)linear MHD wave excitation and propagation. This session will provide a timely platform for joint discussions between world-leading experts, early career researchers and PhD students in solar observational analysis and numerical or analytical modelling.

With our Best Regards,
Malcolm Druett, Viktor Fedun, Wenzhi Ruan, Sergiy Shelyag, Abhishek Srivastava… continue to the full article

Scientific rationale:

This workshop aims at presenting recent research on the longstanding problems of particle acceleration and transport in different astrophysical environments, such as the Sun, the heliosphere, galactic sources, and extragalactic sources. The purpose is to bring together experts in the fields of cosmic ray physics, plasma turbulence, acceleration processes, and particle transport, in order to stimulate cross-fertilization and to exchange scientific information among different areas. Indeed, the basic theoretical framework adopted to describe particle acceleration and transport is common to all those fields but the properties of the environments change noticeably. In addition, in-situ and remote observations often question the validity of the standard theories and call for further investigations. The availability of large datasets from new instrumentation and recent theoretical and numerical studies give the opportunity to advance the models and possibly to answer some of the basic unresolved issues. Exchange of ideas among the various fields would certainly speed up this process.
We strongly encourage to present recent, pioneering observations, theories, and models that try to explain and describe processes of particle acceleration and transport. We try to bring together scientists who would like to understand what is happening beyond their field of specialty.

Main Topics:

Observations of energetic particles in the solar, heliospheric, galactic and extragalactic environments
Properties of cosmic ray transport and acceleration from in-situ and remote observations
Solar flares, Crab flares, flaring phenomena in astrophysics
Shock acceleration: problems and advances
Particle acceleration in magnetic reconnection, including the relativistic regimes
Particle acceleration in black holes, accretion flows, and relativistic jets
Transport and acceleration in non-linear regimes
Magnetic turbulence in astrophysical plasmas: properties from large to small scales and effects on particle transport
Theoretical models and numerical simulations of particle transport and acceleration

Session ST1.7 Theory and Simulation of Solar System Plasmas
https://meetingorganizer.copernicus.org/EGU25/session/53400

The “Theory and Simulation of Solar System Plasmas” session is a forum for presenting recent results related to theoretical and numerical investigation of heliospheric plasmas. Our regions of interest are the Sun and its corona, the solar wind and planetary magnetospheres. Processes of interest are magnetic reconnection, turbulence, shock waves, plasma instabilities, plasma heating and particle acceleration. We particularly welcome studies integrating numerical modeling, theoretical investigations and in-situ measurements or remote observations from current and future space missions (MMS, Parker Solar Probe, Solar Orbiter, Bepi Colombo, ASO-S, Plasma Observatory, HelioSwarm, SMILE, SPO …). Any modeling approach, from global to kinetic, is at home here. We particularly encourage submissions on advances in high resolution global models that reproduce mesoscale phenomena and global modeling that go beyond single fluid MHD (including global hybrid and global MHD models with embedded kinetic domains). The focus of this year’s session is the interplay between global and kinetic-scale processes in heliospheric plasmas: how global drivers results into smaller scale (down to kinetic) processes, and how small scale processes in turn set constraints on global heliospheric observables.

Dear UKSP,

Abstract submission is now open for the following session at EGU 2025 in Vienna, 27th April to 2nd May https://www.egu25.eu/

ST2.5 Wave-particle interactions in terrestrial and planetary radiation belts, magnetospheres and the solar wind
~~~~~~~~~~~~~~~~~~~~~
Generation of electromagnetic waves, their propagation in inhomogeneous active plasma, amplification and absorption by – and interactions with – charged particle populations, generally covered by the term “wave-particle interactions”, are key processes responsible for energy and momentum exchange between charged particles in absence of collisions. New generation of spacecraft missions, PSP, Solar Orbiter, MAVEN, Juno, MMS, ERG/Arase, provide unique and detailed information about wave-particle interactions and their impact on microscopic plasma kinetics as well as contribution to dynamics of macroscopic plasma systems. Observations of these missions of similarity and differences of wave-particle interactions in solar wind, radiation belts, and magnetospheres of different planets drive rapid growth of new theoretical concepts, including effects of nonlinear and nonresonant interactions into more conventional quasi-linear models. This session aims to connect specialists focused on spacecraft observations of different aspects of wave-particle interactions in various space plasma systems and specialists working on the next generation of theoretical models incorporating nonlinear and nonresonant interaction effects.
