进入“磁高速公路”：日球边界的高能粒子各向异性
Entering the "magnetic highway": energetic particle anisotropies at the heliospheric boundary
摘要：
2012年8月，旅行者1号空间探测器进入了一个独特的新空间区域，其特征是实际上没有日光层高能带电粒子和磁场波动，被称为“磁高速公路”。在它们消失之前，粒子分布在90 $^\circ$节距角处强烈地达到峰值，这意味着粒子沿着磁场线更快地逃逸。我们调查的过程中，从日鞘区的粒子交叉到“磁高速公路”地区使用的动力学方法解决尺度的粒子的回旋半径和更小。我们表明，“损失锥”型分布自然出现的轨道粒子进入一个区域的空间具有极低的俯仰角散射率。
英文摘要：
In August of 2012 the Voyager 1 space probe entered a distinctly new region of space characterized by a virtual absence of heliospheric energetic charged particles and magnetic fluctuations, dubbed a "magnetic highway". Prior to their disappearance, the particle distributions strongly peaked at a 90$^\circ$ pitch angle implying a faster particle escape along the magnetic field lines. We investigate the process of particle crossing from the heliosheath region into the "magnetic highway" region using a kinetic approach resolving scales of the particle's cyclotron radius and smaller. We show that a "loss-cone" type distribution naturally arises as the orbiting particles enter a region of space with an extremely low pitch-angle scattering rate.
