Scaling Dynamics of Photospheric Fields and the Problem of Energy Release in the Upper Solar Atmosphere

文章摘要：ATM 99-87305建议标题：光球场的标度动力学和太阳上层大气中的能量释放问题主要研究人员：Ana C.Cadavid研究人员将致力于了解低于观测分辨率的尺度上磁通量、强度和自由能在空间和时间上的演变。主要的努力是将复杂的数学光谱函数与较大尺度的观测结果相匹配，然后外推到低于观测分辨率极限的小尺度，看看可以从加热太阳日冕中学到什么。同时提供太阳风和太阳X射线发射的日冕，到目前为止，维持温度的能量输入还没有牢固地建立起来。具体地说，研究人员将在光球层中分离运动的细胞和湍流成分，这是日冕加热基本问题的主要兴趣所在。尽管磁场脚点偶尔神秘的快速运动对日冕加热有潜在的贡献，但到目前为止，它几乎没有受到关注。这项调查的目的是量化突然运动所产生的能量贡献。

Abstract: ATM 99-87305Proposal Title: Scaling Dynamics of Photospheric Fields and the Problem of Energy Release in the Upper Solar AtmospherePrincipal Investigator: Ana C. Cadavid The investigators will work to understand the evolution in space and time of magnetic flux, intensity and free energy at scales below the resolution of observations. The main effort is to fit sophisticated mathematical spectral functions to the observations of the larger scales and then extrapolate to the small scales below the limit of observational resolution to see what can be learned about heating the solar corona. The corona that provides both the solar wind and the X-ray emission of the Sun and, so far, the energy input that maintains the temperature is not firmly established. Specifically, the investigators will separate the cellular and turbulent components of the motion in the photosphere, which is of prime interest in the basic problem of coronal heating. Occasional mysterious rapid motion of magnetic footpoints has to date received little attention, in spite of its potential contribution to coronal heating. The investigation is intended to quantify the energy contribution that the sudden motions make.
