论文摘要

我们研究了不同瞬态之间的关系,例如在304〜Å拍摄的图像中检测到的相关关系,极端紫外线冠状明亮点(ECBP)在193〜Å,X射线冠状明亮点(XCBPS)在AIA上的94〜Å时,在AIA上的X射线冠状明亮点(XCBPS),以及HMI在多自动鉴定过程中被HMI观察到的。磁功能。使用十年的数据,我们分别检测到总计7,483,827个眨眼,2,082,162个欧洲央行和1,188,839 XCBPS,其出生率约为$ 1.1 \ times10^{ - 18} $ $ $ $ $ $ $ { $ 3.8 \ times10^{ - 19} $ $ {\ rm m}^{ - 2} {\ rm s}^{ - 1} $和$ 1.5 \ times10^{ - 19} $ $ {\ rm m m}我们发现,在超级颗粒的边界上观察到约80%的闪晶,而57 \%(34 \%)与欧洲央行(XCBP)相关。我们进一步发现,大约61个{ - } 80 \%的瞬变与安静的太阳中的孤立磁极有关,并且\ textbf {瞬态的归一化最大强度与PORES的光电磁通量}相关。这些结果明显地表明,这些瞬态具有磁性,它们的同步行为为理解太阳气氛不同层之间的耦合提供了进一步的线索。我们的研究进一步表明,这些瞬变的外观与黑子循环非常抗相关。这一发现可能与在太阳周期内更好地理解在不同尺度上的太阳能发电机和磁性结构有关。

We investigate the relationship between different transients such as blinkers detected in images taken at 304~Å, extreme ultraviolet coronal bright points (ECBPs) at 193~Å, X-ray coronal bright points (XCBPs) at 94~Å on AIA, and magnetic features observed by HMI during ten years of solar cycle 24. An automatic identification method is applied to detect transients, and the YAFTA algorithm is used to extract the magnetic features. Using ten years of data, we detect in total 7,483,827 blinkers, 2,082,162 ECBPs, and 1,188,839 XCBPs, respectively, with their birthrate of about $1.1\times10^{-18}$ ${\rm m}^{-2}{\rm s}^{-1}$, $3.8\times10^{-19}$ ${\rm m}^{-2}{\rm s}^{-1}$, and $1.5\times10^{-19}$ ${\rm m}^{-2}{\rm s}^{-1}$. We find that about 80\% of blinkers are observed at the boundaries of supergranules, and 57\% (34\%) are associated with ECBPs (XCBPs). We further find that about 61{--}80\% of transients are associated with the isolated magnetic poles in the quiet Sun and that \textbf{the normalized maximum intensities of the transients are correlated with photospheric magnetic flux of poles} via a power law. These results conspicuously show that these transients have a magnetic origin and their synchronized behavior provides further clues towards the understanding of the coupling among the different layers of the solar atmosphere. Our study further reveals that the appearance of these transients is strongly anti-correlated with the sunspots cycle. This finding can be relevant for a better understanding of solar dynamo and magnetic structures at different scales during the solar cycle.
