The Voyager mission revealed a complex system of rings and ring arcs around Neptune and uncovered six new satellites, four of which occupy orbits well inside the ring region. Analysis of Voyager data shows that a radial distortion with an amplitude of approximately 30 kilometers is traveling through the ring arcs, a perturbation attributable to the nearby satellite Galatea. Moreover, the arcs appear to be azimuthally confined by a resonant interaction with the same satellite, yielding a maximum spread in ring particle semimajor axes of 0.6 kilometer and a spread in forced eccentricities large enough to explain the arcs' 15-kilometer radial widths. Additional ring arcs discovered in the course of this study give further support to this model.
航海者任务揭示了海王星周围一个复杂的环系和环弧系统，并发现了六颗新卫星，其中四颗卫星的轨道位于环区内部。对航海者数据的分析表明，一个幅度约为 30 公里的径向变形正在穿过环弧，这种扰动归因于附近的卫星加勒底亚。此外，这些弧似乎受到与同一颗卫星的共振相互作用的限制，从而导致环粒子半长轴的最大扩展为 0.6 公里，以及强迫偏心率的扩展足以解释这些弧的 15 公里的径向宽度。在这项研究过程中发现的其他环弧进一步支持了这一模型。
