广义相对论检验中的“印记”?

"Imprinting" in General Relativity Tests?

Lorenzo Iorio

摘要:

我们调查可能的先验“印记”的广义相对论本身的航天器为基础的测试。我们处理一些执行或建议的时间延迟测距实验在太阳的引力场。广义相对论在天文单位和太阳引力常量GM_ \odot上的“印记”,在迄今为止进行的航天器时间延迟测试中还没有得到解决,这可能会在旨在测量空间曲率PPN参数γ的典型太阳系测距实验中引起10^-6量级的先验偏差。它太小了,小了一个数量级,不足以影响卡西尼号的实验,但它会影响未来计划或提议的测试,这些测试旨在达到10^-7-10^-9的精度来确定γ。

英文摘要:

We investigate possible a-priori "imprinting" of general relativity itself on spaceraft-based tests of it. We deal with some performed or proposed time-delay ranging experiments in the Sun's gravitational field. The "imprint" of general relativity on the Astronomical Unit and the solar gravitational constant GM_\odot, not solved for in the so far performed spacecraft-based time-delay tests, may induce an a-priori bias of the order of 10^-6 in typical solar system ranging experiments aimed to measuring the space curvature PPN parameter γ. It is too small by one order of magnitude to be of concern for the performed Cassini experiment, but it would affect future planned or proposed tests aiming to reach a 10^-7-10^-9 accuracy in determining γ.
