已分辨和未分辨磁性元素的光度特性
Photometric properties of resolved and unresolved magnetic elements
摘要：
我们研究了太阳光球层中磁通量管的光度特征。建立了孤立和聚集磁通量管的二维静态数值模型。我们研究了不同空间分辨率和不透明度模型下不同视线的出射光强分布。我们发现，明亮的磁特征的几何和光度特性不仅取决于管及其周围环境的物理特性，而且还取决于观测的特殊性，包括线/连续体形成高度，空间分辨率和应用的图像分析技术。我们表明，在文献中提出的一些观测结果可以解释考虑明亮的磁功能是集群的较小的元素，而不是一个整体的通量管。
英文摘要：
We investigate the photometric signature of magnetic flux tubes in the solar photosphere. We developed two dimensional, static numerical models of isolated and clustered magnetic flux tubes. We investigated the emergent intensity profiles at different lines-of-sight for various spatial resolutions and opacity models. We found that both geometric and photometric properties of bright magnetic features are determined not only by the physical properties of the tube and its surroundings, but also by the particularities of the observations, including the line/continuum formation height, the spatial resolution and the image analyses techniques applied. We show that some observational results presented in the literature can be interpreted by considering bright magnetic features to be clusters of smaller elements, rather than a monolithic flux tube.
