论文摘要
最近，从卡西尼数据发现，土星泰坦的平均衰退速度为$ v = 11.3 \ pm 2.0 $ cm/yr，这与土星的潮汐质量因子$ q \ cong 100 $相对应，而标准估计收益$ q \ ge 6 \ cdot 10^4 $。假设如此巨大的速度$ V $是由于五个内部中型土星的共振机制引起的。在本文中，我们表明，$ V $的基本部分可能来自本地哈勃扩展，其中Hubble-Lema \^ıtre常数$ H_0 $重新计入了土星 - titan距离$ d $ d $为8.15 cm/（Yr $ D $）。我们的假设基于许多其他观察结果，显示了太阳系的略有扩展以及我们的银河系的速度，其速率可与$ h_0 $相当。我们证明，估计$ Q $因子的巨大不成比例可能只是由本地扩展效应引起的。
Recently it was found from Cassini data that the mean recession speed of Titan from Saturn is $v=11.3\pm 2.0$ cm/yr which corresponds to a tidal quality factor of Saturn $Q\cong 100$ while the standard estimate yields $Q\ge 6\cdot 10^4$. It was assumed that such a large speed $v$ is due to a resonance locking mechanism of five inner mid-sized moons of Saturn. In this paper, we show that an essential part of $v$ may come from a local Hubble expansion, where the Hubble-Lema\^ıtre constant $H_0$ recalculated to the Saturn-Titan distance $D$ is 8.15 cm/(yr $D$). Our hypothesis is based on many other observations showing a slight expansion of the Solar system and also of our Galaxy at a rate comparable with $H_0$. We demonstrate that the large disproportion in estimating the $Q$ factor can be just caused by the local expansion effect.
