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.

首席调查员(PI)的团队将计算与日冕物质抛射(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。提议团队将使用CME激波的三维磁流体力学模型，以现实的方式跟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。PI表示，这项研究的结果将有助于开发改进的空间气象工具，以预测太阳事件导致的近地空间辐射环境。PI还指出，冲击波的粒子注入和加速是空间物理和天体物理中尚未解决的重大问题之一。对太阳系中粒子加速和输运的研究将加深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。
