Simulations and multi-vantage-point observations of solar flare energetic electrons

粒子加速是一种普遍存在的宇宙现象。太阳耀斑中的粒子加速就是这类过程的典型例子。尽管研究活跃，但无论是理论上还是观测/现象学上，加速和输运过程都远未得到很好的理解。附近的太阳提供了一个独特的机会，可以通过硬x射线、无线电和太空中的原位观测来研究电子加速和传输。利用观测（太阳轨道器、帕克太阳探测器、RHESSI、费米），将进行理论和数值模拟，以更好地理解太阳电子在太阳处的加速和从太阳到地球的传输。这项调查特别及时，因为新的多点观测比以往任何时候都更接近太阳，这是最近发射的美国宇航局帕克太阳探测器（PSP）和欧洲航天局太阳轨道器（SolO）任务的主要科学目标之一。”

"Acceleration of particles is a ubiquitous cosmic phenomenon. Particle acceleration in solar flares is the prime example of such processes. Despite active research, acceleration and transport processes are far from well understood, either theoretically or observationally/phenomenologically. The nearby Sun offers a unique opportunity to study electron acceleration and transport via hard X-rays, radio and in-situ observations in space. Using the observations (Solar Orbiter, Parker Solar Probe, RHESSI, Fermi), theoretical and numerical modelling will be undertaken to better understand solar electron acceleration at the Sun and transport from the Sun to the Earth. This investigation is particularly timely due to new multi-point observations closer to the Sun than ever before and is one of the main scientific objectives of the recently launched NASA Parker Solar Probe (PSP) and ESA Solar Orbiter (SolO) missions.
