太阳的副色层磁再连接

在太阳上观测到了次表层磁再连接，其位置随着色球层等离子区（从光层到日冕层）的深度而变化。作者通过分析发射线及其密度和温度相关性，探索了活动区 AR 11504 的次表层结构。图中显示了不同日期（左图--2012 年 6 月 14 日 00:58 UT，右图--2012 年 6 月 15 日 00:58 UT）的白光连续面图像，这些图像来自 Deborah Baker 和合作者的研究成果。箭头表示水平磁场的强度和方向。两图中都可以看到光桥的位置，左图（X=-147′′，Y=-292′′附近），右图（X=64′′，Y=-299′′附近）。这些磁场强度足以产生 I-FIP 效应，等离子体参数（如密度和波幅）的进一步分析也证明了这一点。总之，这些都是在形成光桥的磁通管之间区域的偶发加热和再连接外流的特征，因此可以得出结论，光桥很可能是磁再连接的位置。

期刊介绍： Nature Astronomy, the oldest science, has played a significant role in the history of Nature. Throughout the years, pioneering discoveries such as the first quasar, exoplanet, and understanding of spiral nebulae have been reported in the journal. With the introduction of Nature Astronomy, the field now receives expanded coverage, welcoming research in astronomy, astrophysics, and planetary science. The primary objective is to encourage closer collaboration among researchers in these related areas. Similar to other journals under the Nature brand, Nature Astronomy boasts a devoted team of professional editors, ensuring fairness and rigorous peer-review processes. The journal maintains high standards in copy-editing and production, ensuring timely publication and editorial independence. In addition to original research, Nature Astronomy publishes a wide range of content, including Comments, Reviews, News and Views, Features, and Correspondence. This diverse collection covers various disciplines within astronomy and includes contributions from a diverse range of voices.
