论文摘要
在静止的第二个后（2pn）谐波坐标中，确定了静止的身体四极场中光信号的时间延迟。对于阳光下的放牧光线，木星和土星的时间延迟分别为2pn四极效应，分别为0.004、0.14和0.04 pico-second。将这些值与第一个牛顿后（1pn和1.5pn）近似的时间延迟进行了比较，事实证明，只有前八个质量 - 多杆菌和这些巨大物体的自旋偶极性在给定的目标准确性是0.001 pico seceent在Solar System time-delay测量中的给定目标准确性。此外，在准确性的规模上需要木星的自旋己酮。
The time delay of a light signal in the quadrupole field of a body at rest is determined in the second post-Newtonian (2PN) approximation in harmonic coordinates. For grazing light rays at Sun, Jupiter, and Saturn the 2PN quadrupole effect in time delay amounts up to 0.004, 0.14, and 0.04 pico-second, respectively. These values are compared with the time delay in the first post-Newtonian (1PN and 1.5PN) approximation, where it turns out that only the first eight mass-multipoles and the spin-dipole of these massive bodies are required for a given goal accuracy of 0.001 pico-second in time-delay measurements in the solar system. In addition, the spin-hexapole of Jupiter is required on that scale of accuracy.
