太阳辐射压与开普勒轨道偏差
Solar Radiation Pressure and Deviations from Keplerian Orbits
摘要：
牛顿引力论和广义相对论给出了一个物体在围绕静止中心质量的圆形轨道上的周期的完全相同的表达式。然而，当同时考虑时空曲率和太阳辐射压力的影响时，对于太阳帆推进的卫星，存在偏离开普勒第三定律的情况。它表明，太阳辐射压力影响这颗卫星的周期在两个方面：通过有效地减少太阳质量，从而增加的周期，并通过增强其他现象的影响，使其中一些检测。特别是，我们考虑偏离开普勒轨道，由于时空曲率，从太阳的旋转，扁率的太阳，一个可能的净电荷的太阳，和一个非常小的积极的宇宙学常数的帧拖动。
英文摘要：
Newtonian gravity and general relativity give exactly the same expression for the period of an object in circular orbit around a static central mass. However, when the effects of the curvature of spacetime and solar radiation pressure are considered simultaneously for a solar sail propelled satellite, there is a deviation from Kepler's third law. It is shown that solar radiation pressure affects the period of this satellite in two ways: by effectively decreasing the solar mass, thereby increasing the period, and by enhancing the effects of other phenomena, rendering some of them detectable. In particular, we consider deviations from Keplerian orbits due to spacetime curvature, frame dragging from the rotation of the sun, the oblateness of the sun, a possible net electric charge of the sun, and a very small positive cosmological constant.
