SHINE: Injection, Acceleration and Transport of Solar Energetic Particles Produced by the Coronal Mass Ejection (CME) Shock

首席研究员（PI）团队将计算由与日冕物质抛射（cme）相关的冲击波事件引起的太阳高能粒子（sep）的注入和加速。该团队将使用CME冲击的三维磁流体动力学模型，以现实的方式追踪这些冲击波的演变，并计算SEP源粒子在空间中的分布。该团队将获得日冕中SEP源强度和光谱的时空变化，并将这些数据输入到他们的三维行星际粒子传输模型中，用于计算地球和太阳系其他位置的SEP强度。计划指出，这项研究的结果将有助于发展改进的空间气象工具，以预测太阳事件造成的近地空间辐射环境。PI还指出，粒子注入和冲击波加速是空间物理学和天体物理学中尚未解决的重大问题之一。这项对太阳系中粒子加速和传输的研究将增强我们对宇宙中许多其他高能天体物理现象（如宇宙射线、超新星遗迹和伽马射线发射）的理解。此外，该项目还将为一名年轻的博士后科学家提供培训。

The Principal Investigator's (PI's) team will calculate the injection and acceleration of solar energetic particles (SEPs) caused by shock wave events associated with coronal mass ejections (CMEs). The proposing team will use a three-dimensional magnetohydrodynamic model of CME shocks to trace the evolution of these shock waves in a realistic manner and to calculate the SEP source particle distribution in space. The team will obtain the temporal and spatial variation of SEP source intensity and spectra in the solar corona, and input this data into their three-dimensional interplanetary particle transport model for calculation of SEP intensity at Earth and other locations in the solar system.The PI states that the results of this study will assist the development of improved space weather tools to forecast the near-Earth space radiation environment resulting from solar events. The PI also notes that particle injection and acceleration by shock waves is one of the great unsolved problems in space physics and astrophysics. This investigation of particle acceleration and transport in the solar system will enhance our understanding of many other high-energy astrophysics phenomena in the universe (such as cosmic rays, supernova remnants, and gamma-ray emissions). In addition, the project will provide training to a young postdoctoral scientist.
