Space Weather: Implications Arising from the Interaction of Energetic Particles with Shock Waves

对高能粒子加速和调制的基本了解很可能是未来空间天气预报的一个组成部分。这项研究涉及：(1)日冕物质抛射(CME)驱动的激波中粒子的加速，(2)星系宇宙射线与CME复合体的相互作用，以及(3)高能粒子到一个天文单位的输运。PI将开发理论模型，描述快速CME相关激波中高能粒子的扩散加速，以及它们随后通过行星际介质传播到地球的过程。在多维研究的基础上，他还将确定对各种行星际磁场配置的大型质子事件的时间分布和通量强度的详细了解。然后，项目目标将部署建模、分析和MHD模拟的独特组合。

The basic understanding of energetic particle acceleration and modulation is likely to be an integral component of future space weather forecasting. This investigation addresses: (1) the acceleration of particles at coronal mass ejection (CME)-driven shocks, (2) the interaction of galactic cosmic rays with the CME complex, and (3) the transport of energetic particles to one astronomical unit. The PI will develop theoretical models describing the diffusive acceleration of energetic particles at fast CME associated shocks and their subsequent propagation through the interplanetary medium to Earth. Based on a multi-dimensional study, he will also determine a detailed understanding of the time profiles and flux intensities of large proton events for a variety of interplanetary magnetic field configurations. Project goals, then, will deploy a unique blend of modeling, analysis and MHD simulations.
