论文摘要
Prometheus和Pandora对卫星的动态演变是混乱的，短短3。3.3岁的Lyapunov时间。众所周知，普罗米修斯和潘多拉（Prometheus and Pandora）的APSES线的反对准每6.2年发生一次，是一种关键配置，可以放大其混乱的动力学演化。但是，普罗米修斯和潘多拉之间的相互作用不足以解释哈勃太空望远镜观察到的纵向滞后。当前工作的主要目标是确定Prometheus-Pandora对的混乱动力演化的主要贡献者。因此，在这项工作中，我们首先探讨了这种动态系统的敏感性，以数字理解它，然后构建数值实验以实现我们的目标。我们确定，土星系统的几乎所有主要卫星在普罗米修斯和潘多拉的轨道的发展中都起着重要作用。
The dynamical evolution of the Prometheus and Pandora pair of satellites is chaotic, with a short 3.3 years Lyapunov time. It is known that the anti-alignment of the apses line of Prometheus and Pandora, which occurs every 6.2 years, is a critical configuration that amplifies their chaotic dynamical evolution. However, the mutual interaction between Prometheus and Pandora is not enough to explain the longitudinal lags observed by the Hubble Space Telescope. The main goal of the current work is to identify the main contributors to the chaotic dynamical evolution of the Prometheus-Pandora pair beyond themselves. Therefore, in this work, we first explore the sensibility of this dynamical system to understand it numerically and then build numerical experiments to reach our goals. We identified that almost all major satellites of the Saturn system play a significant role in the evolution of Prometheus' and Pandora's orbits.
