Jet phenomena with a bright loop in their footpoint, called anemone jets, have been observed in the solar corona and chromosphere. These jets are formed as a consequence of magnetic reconnection, and from the scale universality of magnetohydrodynamics (MHD), it can be expected that anemone jets exist even in the solar photosphere. However, it is not necessarily apparent that jets can be generated as a result of magnetic reconnection in the photosphere, where the magnetic energy is not dominant. Furthermore, MHD waves generated from the photospheric jets could contribute to chromospheric heating and spicule formation; however, this hypothesis has not yet been thoroughly investigated. In this study, we perform 3D MHD simulation including gravity with the solar photospheric parameter to investigate anemone jets in the solar photosphere. In the simulation, jet-like structures were induced by magnetic reconnection in the solar photosphere. We determined that these jet-like structures were caused by slow shocks formed by the reconnection and were propagated approximately in the direction of the background magnetic field. We also suggested that MHD waves from the jet-like structures could influence local atmospheric heating and spicule formation.

磁重联引起的太阳光球类射流现象的数值模拟

在日冕和色球层中已经观察到在它们的脚点有一个明亮的环的喷射现象，称为海葵喷射。这些射流是磁重联的结果，从磁流体动力学（MHD）的尺度普遍性来看，可以预期即使在太阳光球层中也存在海葵射流。然而，作为光球层中磁重联的结果，射流不一定很明显，其中磁能不占主导地位。此外，光球射流产生的 MHD 波可能有助于色球加热和骨针形成；然而，这一假设尚未得到彻底调查。在这项研究中，我们执行 3D MHD 模拟，包括具有太阳光球参数的重力，以研究太阳光球层中的海葵喷射。在模拟中，太阳光球层中的磁重联诱导了射流状结构。我们确定这些喷射状结构是由重新连接形成的缓慢冲击引起的，并且大约在背景磁场的方向上传播。我们还提出，来自喷射状结构的 MHD 波可能会影响局部大气加热和骨针形成。
