The Principal Investigator's team will investigate solar active region dynamics, utilizing a novel data analysis technique involving vector magnetograms as well as data-driven magnetohydrodynamic simulations, to quantitatively assess the physics of force balance and imbalance, magnetic energy content, and relevant non-potential features in solar active regions. The results will produce a non-force-free magnetic solution consistent with vector magnetograms and with observed coronal loop structures observed in the extreme ultraviolet. This study will exploit the best available space-based and ground-based observations for magnetography and coronal loop imagery, with the goal to enhance both our physical understanding and predictive capabilities for non-force-free magnetic fields in solar active regions.These results will help predict the dynamics of the solar atmosphere and the likelihood of occurrence of flares and coronal mass ejections, and thus it will have positive impact on space weather forecasting capabilities. In this effort, the Center for Space Plasma and Aeronomic Research (CSPAR) at the University of Alabama at Huntsville will collaborate with the Solar Physics group at NASA's Marshall Space Flight Center to explore the development of spacecraft instrumentation that could be flown on new major NASA solar missions. In this way, the CSPAR faculty will develop the expertise needed to build and sustain a critical mass research group at the University, enhancing the education and training of future space physicists there. The team will also engage the under-served and under-represented student population in the Huntsville community in collaboration with Alabama A&M University, a minority-serving institution, by hiring undergraduate and graduate students as summer interns in order to enhance their research experience in space science.

首席研究员的团队将研究太阳活动区动态，利用涉及矢量磁图以及数据驱动的磁流体动力学模拟的新型数据分析技术，定量评估力平衡和不平衡，磁能含量和相关的物理学太阳活动区的非潜在特征。结果将产生一个非力自由磁解与矢量磁图和观测到的极紫外日冕环结构一致。这项研究将利用现有的最佳天基和地基观测资料进行磁测和日冕环成像，目的是加强我们对太阳活动区非无力磁场的物理认识和预测能力，这些结果将有助于预测太阳大气的动态以及发生耀斑和日冕物质抛射的可能性，从而对空间天气预报能力产生积极的影响。在这项工作中，亨茨维尔的亚拉巴马大学空间等离子体和空气动力学研究中心将与美国航天局马歇尔空间飞行中心的太阳物理学小组合作，探索开发可用于美国航天局新的重大太阳任务的航天器仪器。通过这种方式，CSPAR教师将发展在大学建立和维持临界质量研究小组所需的专业知识，加强那里未来空间物理学家的教育和培训。该小组还将与亚拉巴马A M大学（一所为少数群体服务的机构）合作，雇用本科生和研究生作为暑期实习生，以增强他们在空间科学方面的研究经验，从而使亨茨维尔社区服务不足和代表性不足的学生群体参与进来。
