“嫦娥一号”卫星观测近月太阳风离子特征
Features of solar wind ions near the Moon observed by spacecraft Chang'E-1
摘要
Abstract
The solar wind ions detectors onboard the spacecraft Chang'E-1 (CE-1) have made a great contribution in advancing the understanding of the solar wind-Moon interaction and the induced near-Moon plasma environment.Several features of solar wind ions near the Moon were observed by the CE-1 on Dec 30,2007:1) both protons (H+) and alpha particles (He2+) were identified in the slow solar wind;2) the accelerated solar wind pickup ions were repeatedly observed on the lunar dayside under the nterplanetary magnetic field (IMF) By dominant conditions; 3) the accelerated pickup ions show being angle-dependent clearly and location-dependent sensitively; 4) under the IMF positive (negative) By conditions,the decelerated (accelerated) solar wind H+ intruded deep into the wake from the wake boundary in the northern hemisphere,while the He2+ population intruded less deep than H+.The revelation of these features may be of great help to understand the near-Moon plasma environment.关键词
