摘要
利用光引力理论得到了光引力限制性三体问题的特解,并将研究结果应用到太阳系天体,探讨了太阳光引力对彗尾运动的影响。结果表明对于等离子体彗尾只有1个直线平动点L3,对于某些尘埃彗尾可以有2个共面平动点L6,L7和3个直线平动点L21,L22,L3,并给出了存在其面平动点的范围。由此还可以确定尘埃彗尾可能的运动区域。
On the basis of photguitational theory, the special solutions of the photogravitational restricted three-body problem are obtained-Applving fthe results obtained in this paper, we also discuss the influence of solar photoguitation on the moion of come tail. lt is shown that for plasrna tall of comet there are only one collinear point L, and for a few of dust tail there can be two coplanar points L6, L7 and three collinear points L21, L22, L3. The regions in which there are coplanar points and the dust grain of comettail can move are also obtained.
