Debi Prasad Choudhary, Gordon A. MacDonald, Toshifumi

摘要:

利用日之出太阳光学望远镜的观测资料,我们研究了16个不同大小和形状的太阳黑子。G-带和CaII H图像的比值揭示了大多数斑点的本影和半影内的丰富结构。突出的特征是在半影原纤维的本影侧的足点处的紧凑的斑点,具有盘中心-肢侧不对称性。在本文中,我们提出了这些功能的性质,使用分光偏振和图像在G波段,钙和蓝色过滤器。我们讨论的结果使用当代模型的太阳黑子。

英文摘要:

We studied 16 sunspots with different sizes and shapes using the observations with the Hinode Solar Optical Telescope. The ratio of G-band and CaII H images reveal rich structures both within the umbra and penumbra of most spots. The striking features are the compact blob at the foot point of the umbra side of the penumbral fibrils with disk center-limb side asymmetry. In this paper, we present properties of these features using the spectropolarimetry and images in G-band, CaII and blue filters. We discuss the results using the contemporary models of the sunspots.
