将Yukawa类修正引力(MOG)用于太阳系的测试
Putting Yukawa-like Modified Gravity (MOG) on the test in the Solar System
摘要:
我们处理一个Yukawa像远程修改模型的重力(MOG),最近允许成功地容纳许多天体物理和宇宙学的功能,而不诉诸暗物质。在太阳系尺度上,MOG预测了行星近日点\varpi的逆行长期岁差,它的存在已经在这里通过观测估计的Pitjeva修正与不同行星对的标准牛顿/爱因斯坦近日点岁差的比率进行了测试。事实证明,MOG在目前的形式下,在天体物理尺度上是现象学上成功的,在太阳系中被排除在3sigma以上的水平。如果其他天文学家团队能够独立地估算出他们自己的近日点额外岁差,那么就有可能重复这样的测试。
英文摘要:
We deal with a Yukawa-like long-range modified model of gravity (MOG) which recently allowed to successfully accommodate many astrophysical and cosmological features without resorting to dark matter. On Solar System scales MOG predicts retrograde secular precessions of the planetary longitudes of the perihelia \varpi whose existence has been put on the test here by taking the ratios of the observationally estimated Pitjeva's corrections to the standard Newtonian/Einsteinian perihelion precessions for different pairs of planets. It turns out that MOG, in the present form which turned out to be phenomenologically successful on astrophysical scales, is ruled out at more than 3sigma level in the Solar System. If and when other teams of astronomers will independently estimate their own extra-precessions of the perihelia it will be possible to repeat such a test.
