摘要

光球漩涡调解太阳内部能量的转移和转换。这些漩涡是通过基于算法的方法在光球观测中识别出来的，但它们在不同太阳状态下的空间分布仍然不清楚。在最近的一项研究中，谢泉及其同事分析了一个光球图像数据集，发现8424个小规模漩涡集中在与颗粒的时空排列相对应的中颗粒间通道（特殊的太阳对流能量转移模式）上。一种自动漩涡检测算法被用于从太阳中心子午线附近安静区域的高分辨率光球观测中识别漩涡。顺时针和逆时针漩涡的数量没有显著差异，但漩涡的速度分布和大小显示了一些有趣的特征——例如，速度范数、转速和膨胀/收缩速度都遵循高斯分布。这种特殊的模式表明涡旋在特定的空间和能量尺度上被激发，支持了大多数涡旋位于中粒间通道的观点。旋转速度、膨胀/收缩速度和环流也随旋流半径呈线性增加，表明空间和能量尺度的特定触发机制。

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.
