辐射压对广义光引力限制三体问题平衡点的影响
The Effect of Radiation Pressure on the Equilibrium Points in the Generalised Photogravitational Restricted Three Body Problem
摘要：
对平衡点的存在性和辐射压的影响进行了数值讨论。将大基色看作辐射源，小基色看作扁球体，将问题推广。我们还讨论了由于辐射压引起的坡印廷-罗伯逊（P-R）效应。发现共线点$L_1,L_2,L_3$偏离了连接两个基色的轴，而三角形点$L_4,L_5$由于辐射压力而不对称。在不考虑P-R效应的情况下，$L_1,L_2,L_3$是线性不稳定的，而$L_4,L_5$是条件稳定的.我们发现，辐射压力的影响减少了线性稳定区，而P-R效应导致了李雅普诺夫意义下的不稳定性。
英文摘要：
The existence of equilibrium points and the effect of radiation pressure have been discussed numerically. The problem is generalized by considering bigger primary as a source of radiation and small primary as an oblate spheroid. We have also discussed the Poynting-Robertson(P-R) effect which is caused due to radiation pressure. It is found that the collinear points $L_1,L_2,L_3$ deviate from the axis joining the two primaries, while the triangular points $L_4,L_5$ are not symmetrical due to radiation pressure. We have seen that $L_1,L_2,L_3$ are linearly unstable while $L_4,L_5$ are conditionally stable in the sense of Lyapunov when P-R effect is not considered. We have found that the effect of radiation pressure reduces the linear stability zones while P-R effect induces an instability in the sense of Lyapunov.
