论文摘要
在太阳风中观察到的动力学尺度电流板通常近似无力，尽管它们的等离子体$β$是一个。现场测量最近表明，血浆密度和温度在电流板上通常会有所不同，而等离子体压力大约均匀。在许多情况下，相对于当前纸的中心，这些密度和温度变化是不对称的。从理论上讲，我们在本文中开发了这些观察结果，该论文的平衡是具有等离子体密度和温度梯度的无力电流板。这些模型也可用于分析太阳风中电流板的稳定性和耗散。
Kinetic-scale current sheets observed in the solar wind are frequently approximately force-free despite the fact that their plasma $β$ is of the order of one. In-situ measurements have recently shown that plasma density and temperature often vary across the current sheets, while the plasma pressure is approximately uniform. In many cases these density and temperature variations are asymmetric with respect to the center of the current sheet. To model these observations theoretically we develop in this paper equilibria of kinetic-scale force-free current sheets that have plasma density and temperature gradients. The models can also be useful for analysis of stability and dissipation of the current sheets in the solar wind.
