论文摘要
Chandrasekhar于1956年发现的非线性无线磁场是一个罕见的无线磁场的一个例子，它描述了轴对称磁场线的大型相干结构，并在Alfvén波的存在下具有漩涡。我们证明，在轴对称Leray-HOPF溶液的弱理想限制方面，他的行驶波解决方案在理想MHD中具有轨道稳定。
Chandrasekhar's nonlinear force-free field, discovered in 1956, is a rare example of a nonlinear force-free field describing a large coherent structure of axisymmetric magnetic field lines with swirls in the presence of Alfvén waves. We demonstrate that his traveling wave solution is orbitally stable with the energy norm in ideal MHD regarding weak ideal limits of axisymmetric Leray-Hopf solutions.
