论文摘要
Alfvén波负责磁化等离子体中磁能的转移。他们参与加热太阳大气，并通过各种非线性过程驱动太阳风。由于磁场构型直接影响Alfvén波的非线性，因此重要的是研究它们如何通过Alfvén波的非线性传播与太阳大气和风结构相关。在这项研究中，我们进行了一维磁水动力学模拟，以实现上述关系。结果表明，当染色体中的Alfvén波的非线性超过临界值时，太阳能球的动力学（例如Spicule）的动力学（例如，Spicule）和太阳风的质量损失率往往与Photosphere的能量输入无关。在Alfvén波高度非线性的情况下，在色层中产生的强剪切扭转流``骨折''磁通管。这对应于色球中间冲击的形成，这限制了通过Alfvén波限制了po频通量进入电晕的传播，还抑制了色球慢性冲击的传播。
Alfvén waves are responsible for the transfer of magnetic energy in the magnetized plasma. They are involved in heating solar atmosphere and driving solar wind through various nonlinear processes. Since the magnetic field configurations directly affect the nonlinearity of Alfvén waves, it is important to investigate how they relate to the solar atmosphere and wind structure through the nonlinear propagation of Alfvén waves. In this study, we carried out the one-dimensional magnetohydrodynamic simulations to realize the above relation. The results show that when the nonlinearity of Alfvén waves in the chromosphere exceeds a critical value, the dynamics of the solar chromosphere (e.g., spicule) and the mass loss rate of solar wind tend to be independent of the energy input from the photosphere. In a situation where the Alfvén waves are highly nonlinear, the strong shear torsional flow generated in the chromosphere ``fractures'' the magnetic flux tube. This corresponds to the formation of chromospheric intermediate shocks, which limit the transmission of the Poynting flux into the corona by Alfvén waves and also inhibits the propagation of chromospheric slow shock.
