论文摘要
行星环通常被推测为巨型行星的相对常见属性，部分基于它们在太阳系中的流行。但是，它们的形成和可持续性仍然是公开讨论的话题，而我们行星系统中最庞大的星球则是一个非常适中的环系统。在这里，我们介绍了N体模拟的结果，该模拟探讨了木星的大量环材料的动态约束。我们的模拟从刚性卫星的Roche限制范围内扩展到木星山半径的10 \％，并将结果从$ 10^6 $和$ 10^7 $ Year $ YearS集成中包括在内。结果表明，木星周围持续致密的环材料存在可能构成了月球形成的基础。结果在很大程度上证明了加利利卫星施加的稳定轨道的截断，以及在$ \ sim $ \ sim $ 3--29 jupiter radii范围内的密集环材料的动态干燥。我们讨论了这些结果对系外行星的含义，以及同时存在环与庞大的月球系统之间的复杂关系。
Planetary rings are often speculated as being a relatively common attribute of giant planets, partly based on their prevalence within the Solar System. However, their formation and sustainability remain a topic of open discussion, and the most massive planet within our planetary system harbors a very modest ring system. Here, we present the results of a N-body simulation that explores dynamical constraints on the presence of substantial ring material for Jupiter. Our simulations extend from within the rigid satellite Roche limit to 10\% of the Jupiter Hill radius, and include outcomes from $10^6$ and $10^7$ year integrations. The results show possible regions of a sustained dense ring material presence around Jupiter that may comprise the foundation for moon formation. The results largely demonstrate the truncation of stable orbits imposed by the Galilean satellites, and dynamical desiccation of dense ring material within the range $\sim$3--29 Jupiter radii. We discuss the implications of these results for exoplanets, and the complex relationship between the simultaneous presence of rings and massive moon systems.
