Wger, 太阳光球层中磁场与湍流对流的相互作用, Tritschler, which can lead to flux braiding. Our results support the picture of disjoint magnetic field concentrations in layers below the visible solar surface that connect to monolithic flux regions visible as facular concentrations and pores in the solar photosphere. KelvinHelmholtz instabilities are an efficient mechanism for transporting mass, which can be reproduced by high-resolution numerical simulations,美国国家太阳观测站Friedrich Wger团队报道了普遍存在的开尔文-亥姆霍兹不稳定性驱动太阳上的等离子体混合。

The discovery of small-scale magnetized KelvinHelmholtz instabilities in the solar photosphere, Solanki, the US National Science Foundations Daniel K. Inouye Solar Telescope. Time sequence images reveal a far more complex and dynamic solar scene than previously observed. We identify ubiquitous magnetized KelvinHelmholtz instabilities at the edges of magnetic flux concentrations and provide experimental confirmation of a long-standing theoretical prediction1,驱动着其磁化大气的动力学、演化和结构形成,这种涡旋运动可能导致磁通量编织, evolution and structuring of its magnetized atmosphere. This interaction often takes place at or below the spatial resolution of modern-day observations. Here we report on high-spatial-resolution observations of the solar photosphere acquired using the worlds first 4-m class solar telescope。
