Active Region Formation and Magnetic Energy Dissipation

9311937麦克莱蒙这个项目的重点是从理论上了解活动区和产生磁场的太阳发电机之间的关系，以及太阳耀斑中磁自由能的耗散。这项研究包括磁通量浮现的研究，目的是确定次光球磁场的通量管模型是否能够解释观测到的活动区发展特征，以及日冕中磁重联的研究，目的是了解重联率随电阻率的变化，气体压力对电流片形成的影响，以及不可压缩流体中的磁重联与无压流体中的重联之间的关系。这项研究将有助于更好地理解太阳活动区的形成和演化。***

9311937 McClymont This project focuses on obtaining a theoretical understanding of the relationship between active regions and the solar dynamo in which the magnetic fields, and possibly free energy, are generated, and the dissipation of magnetic free energy in solar flares. The investigation encompasses a study of flux emergence, with the goal of determining whether a flux tube model of the sub photospheric magnetic field can explain observed characteristics of active region development, and a study of magnetic reconnection in the corona, with the aim of understanding the scaling of the reconnection rate with resistivity, the effect of gas pressure on current sheet formation, and the relationship between magnetic reconnection in an incompressible fluid and reconnection in a pressureless fluid. This research will lead to a greater understanding of the formation and evolution of active regions of the sun. ***
