项目摘要
This team proposes a three-year research program to use state-of-the-art composition measurements from Advanced Composition Explorer (ACE) and Wind (and possibly STEREO (Solar Terrestrial Relations Observatory) near 1 AU, Ulysses at high-and-low solar latitudes, and Cassini en route to Saturn) to model the temporal and spatial evolution of the suprathermal ion population in the 3D-heliosphere between ~1 and 10 AU. The proposers plan to develop a theoretical framework for understanding the main causes of the variability of the suprathermal tail and model its dynamical properties through the inner heliosphere. They also plan to investigate the effects of the inherent variability of the suprathermal tail on coronal mass ejection (CME) shock-associated ion populations in the heliosphere. The resultant numerical model will provide a realistic prescription for the dynamical properties of the suprathermal seed population through the inner heliosphere and could ultimately be utilized by future end-to-end global models of CME initiation, evolution, propagation, and solar energetic particle (SEP) acceleration. The proposed work also will probe, for the first time, the spatial and temporal dependence of stochastic acceleration mechanisms that produce suprathermal ions in the inner heliosphere. This will provide a sound basis for enabling broader theoretical investigations involving the production of suprathermal ions at a variety of astrophysical sites, including the termination shock, solar flares, and supernova shocks. This effort could also aid the development of a global space weather monitoring system to accurately predict radiation levels during CME/SEP events. Several graduate and undergraduate students will be partially supported through this project. The proposers have established a strong record of mentoring students.
该团队提出了一项为期三年的研究计划,利用先进成分探测器(ACE)和Wind(可能还有STEREO(太阳地球关系观测站)在1个天文单位附近,尤利西斯在太阳高纬度和低纬度,卡西尼号在前往土星的路线上)的最先进的成分测量来模拟在1到10个天文单位之间的3d日球层中超高温离子群的时空演变。研究人员计划建立一个理论框架来理解超热尾变化的主要原因,并通过内日球层模拟其动力学特性。他们还计划研究超热尾的固有变异性对日球层日冕物质抛射(CME)冲击相关离子数量的影响。所得到的数值模型将为通过内日球层的超热种子种群的动力学特性提供一个现实的公式,并最终可用于未来的CME起始、演化、传播和太阳高能粒子(SEP)加速的端到端全球模型。提出的工作还将首次探索在内日球层产生超热离子的随机加速机制的时空依赖性。这将为更广泛的理论研究提供坚实的基础,这些研究涉及在各种天体物理地点产生超热离子,包括终端激波、太阳耀斑和超新星激波。这项工作还可以帮助开发全球空间天气监测系统,以准确预测CME/SEP事件期间的辐射水平。一些研究生和本科生将通过这个项目获得部分资助。提案人在指导学生方面有着良好的记录。
