SHINE: Solar Wind with a Time-dependent, MHD, Interplanetary Scintillation Tomography

这个为期3年的SISH计划的主要目标是在全球范围内定位围绕太阳的日球层结构，确定它们与日光层速度和密度的关系，并以物理上一致的方式将它们追溯到太阳。这项研究项目与国家空间气象目标之一直接相关，即“确定喷发事件和太阳之间的联系，并加强对太阳风地效事件的理解和预测。”该项目将在模拟太阳系内部和其他地方复杂的、湍流的气体系统(包括带电的和中性的)方面向前迈出重要的一步。通过多个物理过程的自洽结合来发展包含“耦合复杂性”的物理模型被视为当前十年不同等离子体物理领域的关键发展。这项研究工作还将在阿拉巴马大学亨茨维尔分校和加州大学圣地亚哥分校内促进等离子体物理和计算科学的发展方面发挥领导作用。此外，通过培训广泛的学生、科学家和工程师，该项目将促进阿拉巴马州的空间物理研究。该SLARE项目的研究和EPO议程支持AGS部门在发现、学习、多样性和跨学科研究方面的战略目标。该SHARE项目的主要目标是开发和利用一种新的太阳风MHD(磁流体动力学)-IPS(行星际闪烁)层析成像工具，以研究太阳风(SW)的等离子体和磁场的演化以及从临界点向外到日心距离1-5AU的湍流起伏。该小组将研究日冕物质抛射(CME)向遥远的西南方向的传播，特别关注日冕物质抛射内部的磁场结构，这对地球效应事件特别重要。此外，通过执行数值模拟，日冕物质抛射将通过真实的西南背景传播到将分布与航天器数据进行比较的点。这将使研究人员能够调查日冕物质抛射和其他瞬变事件对地球和星际环境的影响，并有助于制定未来星际任务的安全要求。这对于他们研究“日冕物质抛射的太阳周期依赖性，包括它们通过背景西南光的传播和相互作用，包括星际现象和近太阳现象之间的联系，”是一项宝贵的财富，正如美国国家科学基金会的太阳光辉计划的目标所述。

The main goal of this 3-year SHINE project is to locate heliospheric structures globally around the Sun, determine their relationship to the heliospheric velocity and density, and trace them back toward the Sun in a physically consistent way. This research project is directly related to one of the National Space Weather goals, namely "to determine the connections between eruptive events and the Sun, and to enhance both the understanding and predictions of solar wind geo-effective events." This project would yield a major step forward in the simulation of complex, turbulent gas systems (both charged and neutral) in the inner Solar System and elsewhere. The development of physical models that embrace "coupling complexity" via the self-consistent incorporation of multiple physical processes is viewed as a pivotal development in the different plasma physics areas for the current decade. The research effort will also provide leadership in promoting plasma physics and computational science within the University of Alabama in Huntsville and the University of California in San Diego campuses. Furthermore, through the training of a broad spectrum of students, scientists and engineers, the project will foster Space Physics research within the State of Alabama. The research and EPO agenda of this SHINE project supports the Strategic Goals of the AGS Division in discovery, learning, diversity, and interdisciplinary research.The main objective of this SHINE project is to develop and utilize a new MHD (magnetohydrodynamic) - IPS (interplanetary scintillations) tomography tool of the solar wind (SW) in order to investigate the evolution of the SW plasma and magnetic field, as well as turbulent fluctuations, from distances beyond the critical point outwards to heliocentric distances of 1-5 AU. The team will study the propagation of Coronal Mass Ejections (CMEs) into the distant SW, paying particular attention to the magnetic field structure inside CMEs, which is of particular importance for geo-effective events. Moreover, by way of performing the numerical simulations, the CMEs will be propagating through a realistic SW background to the points where the distributions will be compared with the spacecraft data. This will allow the researchers to investigate the effect of CMEs and other transient events on the Earth and interplanetary environment, and help formulate the safety requirements for future interplanetary missions. This makes it a valuable asset for their investigation of "the solar cycle dependence of CMEs, including their propagation through and their interaction with the background SW, including the linking of interplanetary and near-Sun phenomena," as stated in the goals of the NSF's SHINE program.
