We invite abstract submissions for the session titled “Energetic Particle Acceleration in the Sun and the Heliosphere” (EPASunHelio) at the National Astronomy Meeting 2026 at the University of Birmingham, UK (20th – 24th July). Please use the following link:
Abstract submission closes at 23:45 on 2nd of April
Session details:
Activity at the Sun drives dynamics throughout the heliosphere, and energetic particles form a significant component of energy transfer from the Sun. This has implications for space weather and for ground based electronics. Ground based radio observations, along with recent missions such as Solar Orbiter (SolO) and Parker Solar Probe (PSP), have together offered new insight into the processes involved in particle acceleration, and continue to be valuable sources of data on particle propagation in the corona and heliosphere. Additionally the proposed Solar Particle Acceleration, Radiation and Kinetics (SPARK) mission aims to combine imaging and spectroscopy across EUV, X-ray and gamma ranges to constrain the properties of energetic particles and their source. Fostering collaboration between researchers from observational and theoretical backgrounds across many energy ranges is crucial for bringing together relevant expertise for future missions.
This session will aim to discuss both in-situ and remote sensing observations of these particles, including radio, EUV and X-ray instruments located throughout the heliosphere. The session will discuss how physical modelling plays a key part in the investigation of energetic particles, and can be refined and constrained by the observational results. The session invites speakers from observational and theoretical communities studying energetic particles in the corona and heliosphere to share their work and expertise.
