| 摘 要： | 采用理想的二维单流体MHD方程,对太阳风通过月球时所形成的尾迹结构进行数值模拟,得到了太阳风尾迹的粒子分布及磁场分布.模拟结果表明,在月球背阳面的本影区,太阳风粒子密度急剧下降,行星际磁场增强.当行星际磁场与太阳风流动方向平行时,尾迹被拖得很长,而磁场与太阳风流动方向垂直时,尾迹较短.

| Abstract: | Two-dimentional ideal MHD simulation of the interaction between the solar wind and the Moon reveals the particle and magnetic field distribution in the lunar wake.The results show that the density of the solar wind falls dramatically and the interplanetary magnetic field increases in the umbra of the Moon.When the interplanetary magnetic field is parallel to the direction of the solar wind velocity,the wake is very long.When the magnetic field is normal to the velocity of the solar wind,the wake is shorter. |
