Using Scaling Laws to Constrain Magneto-Thermal Coupling in Active Regions of the Sun with Multi-wavelength Microwave Imaging

来自新泽西理工学院的一个研究小组推进了我们对日冕如何被加热的理解。 人们提出了许多日冕能量释放的机制。该项目将研究太阳活动区的热和磁特性及其与日冕的联系。该项目将使用扩展欧文斯谷太阳能电池阵列（EOVSA）的观测结果与3D数值模拟相结合。该项目符合NSF的使命，通过解决太阳物理学中的一个基本问题来推进科学。它还有助于了解太阳环境，从而有助于更好地了解空间气象这一国家优先事项。该项目包括高中生和研究生的参与，并利用GX模拟器，该模拟器已被证明在吸引学生参与研究方面取得了成功。具体而言，该项目将解决从活动区（AR）到日冕的热结构和磁结构的耦合。这将通过模拟日冕磁场和等离子体特性来实现，然后将其与观测结果进行比较。日冕磁场的三维结构将被量化。AR演变将通过将日冕磁场与热等离子体的地图相结合，并利用EOVSA和天基源的数据验证这些地图来进行检查。这些3D地图将被用来约束标度律，这将被研究对日冕加热机制的约束。最后，这将被用来研究磁场能量是如何积累和演变的。所采用的代码包括用于生成AR三维模型的自动模型生产管道（AMPP）、独立的非线性自由力场（NLFFF）代码和上述GX Simulator.This奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

A research team from the New Jersey Institute of Technology advance our understanding of how the solar corona is heated. Many mechanisms for energy release in the solar corona have been proposed. This project would examine both thermal and magnetic properties of solar active regions and their connection to the solar corona. The project will be carried out using observations from the Extended Owens Valley Solar Array (EOVSA) combined with 3D numerical simulations. This project meets NSF’s mission to advance science by tackling a fundamental problem in solar physics. It also contributes to understanding of the solar environment, which contributes to the national priority to better understand space weather. The project includes participation by high school and graduate students and makes use of the GX Simulator, which has already proved successful in engaging students in research. Specifically, this project will address the coupling of thermal and magnetic structures from active regions (ARs) to the corona. This will be achieved by modeling coronal magnetic fields and plasma properties, which will then be compared with observations. The 3D structure of the coronal magnetic field will be quantified. AR evolution will be examined by combining maps of the coronal magnetic field with thermal plasma and validating these maps with data from EOVSA and space-based sources. These 3D maps will then be used to constrain scaling laws, which will be investigated for constraints on the coronal heating mechanisms. Finally, this will be used to examine how magnetic field energy accumulated and evolves. The codes employed include the Automated Model Production Pipeline (AMPP) for generating 3D models of ARs, a stand-alone Non-Linear Force Free Field (NLFFF) code, and the above mentioned GX Simulator.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
