From Earth’s Magnetospheres to the Outer Heliosphere & Beyond

  • 摘要: 在太阳系中,地球、水星、木星、土星、天王星和海王星以及多颗行星的卫星,拥有由太阳风与这些天体的内在磁场相互作用形成的磁层结构。主要根据现有的探测器得到的数据,介绍了太阳风与星际介质的相互作用、能量中性原子分布和拾起粒子相对空间密度变情况、异常宇宙线的形成机制、日球层可能的形状变化。给出了中国太阳系边际探测计划,设计两个相反方向的探测器,一个向日球层鼻尖方向飞行,对太阳系边际及其邻近空间开展全面的探测;另一个探测器向相反方向飞行,填补日球层尾部边界探测的空白。对日球层的空间环境的认识可为探测器的设计提供参考。
