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域动力学，利用涉及矢量磁图以及数据驱动的磁性水力动力学模拟的新型数据分析技术，以定量评估力平衡和失衡，磁能含量和相关的非关键特征的物理学在太阳活动区域。该结果将产生与载体磁图一致的非无力磁溶液，并与观察到的冠状环结构在极端紫外线中观察到的冠状环结构。这项研究将利用最佳可用空间和地面观测来用于磁性和冠状环图像，其目标是增强我们对太阳能活动区域中非磁性磁场的物理理解和预测能力。有助于预测太阳大气的动力学以及发生耀斑和冠状质量弹出的可能性，因此它将对太空天气预测能力产生积极影响。在这项工作中，阿拉巴马大学亨茨维尔大学的太空等离子体和气压研究中心（CSPAR）将与NASA Marshall太空飞行中心的太阳能物理集团合作，以探索可以在新的NASA少校飞行的航天器仪器的开发太阳能任务。通过这种方式，CSPAR教职员工将开发在大学建立和维持批判性群众研究小组所需的专业知识，从而增强了那里未来太空物理学家的教育和培训。该团队还将与少数派服务机构的阿拉巴马州A＆M大学合作，将服务不足和代表性不足的学生群体与亨茨维尔社区合作，通过雇用本科生和研究生为暑期实习生，以增强他们在太空中的研究经验科学。
