太阳活动变率的行星理论

The planetary theory of solar activity variability: a review

Nicola Scafetta, Antonio Bianchini

摘要:

在评论11年的太阳黑子周期时,Wolf(1859,MNRAS 19,85-86)指出“黑子频率的变化取决于金星、地球、木星和土星的影响”。我们的行星系的高度同步性已经很好地揭示了行星轨道半径的比率通过缩放镜像对称方程彼此密切相关的事实(银行和Sundetta,前。宇航员。太空科学。8,758184,2022)。回顾许多行星谐波和轨道不变的不平等,表征行星运动的太阳系从每月到千年的时间尺度,我们表明,它们不是随机分布的,但显然倾向于集群周围的一些特定的值,也匹配那些主要的太阳活动周期。在某些情况下,行星模型甚至能够预测太阳振荡的时间相位,包括施瓦贝11年太阳黑子周期。我们还强调,太阳模型的基础上的假设,太阳活动是由其内部动力学调节单独从来没有能够重现所观察到的周期的变化。虽然行星的引潮力很弱,我们回顾了一些机制,可以解释如何太阳结构和太阳发电机可以得到调整的行星运动。特别是,我们讨论了如何弱引潮力的影响可能会显着放大在太阳能核心的诱导增加的H-燃烧。还讨论了调制行星系电磁和引力大尺度结构的机制。

英文摘要:

Commenting the 11-year sunspot cycle, Wolf (1859, MNRAS 19, 85-86) conjectured that "the variations of spot frequency depend on the influences of Venus, Earth, Jupiter, and Saturn". The high synchronization of our planetary system is already nicely revealed by the fact that the ratios of the planetary orbital radii are closely related to each other through a scaling-mirror symmetry equation (Bank and Scafetta, Front. Astron. Space Sci. 8, 758184, 2022). Reviewing the many planetary harmonics and the orbital invariant inequalities that characterize the planetary motions of the solar system from the monthly to the millennial time scales, we show that they are not randomly distributed but clearly tend to cluster around some specific values that also match those of the main solar activity cycles. In some cases, planetary models have even been able to predict the time-phase of the solar oscillations including the Schwabe 11-year sunspot cycle. We also stress that solar models based on the hypothesis that solar activity is regulated by its internal dynamics alone have never been able to reproduce the variety of the observed cycles. Although planetary tidal forces are weak, we review a number of mechanisms that could explain how the solar structure and the solar dynamo could get tuned to the planetary motions. In particular, we discuss how the effects of the weak tidal forces could be significantly amplified in the solar core by an induced increase in the H-burning. Mechanisms modulating the electromagnetic and gravitational large-scale structure of the planetary system are also discussed.
