论文摘要
这项研究探讨了冥王星与其月亮夏隆之间的重力相互作用，这导致了他们的同步轨道，在那里他们始终如一地互相表现出同一面孔。这个过程称为潮汐进化，它解释了两个天体之间的重力拉力如何调节其旋转速度，直到它们匹配其轨道速度。通过模拟各种初始条件，我们旨在了解冥王星和夏隆可能采取的特定路径以达到当前阶段。我们观察到它们的轨道倾斜具有可忽略的长期作用，通常会迅速稳定。在我们的分析中，我们检查了一种方案，当轨道大小最初增加时，导致轨道增加和高偏心率，这是归因于潮汐能量的耗散的现象。
This study explores the gravitational interaction between Pluto and its moon Charon, which has led to their synchronous orbit, where they consistently show the same face to each other. This process is known as tidal evolution, which explains how the gravitational pull between two celestial bodies can adjust their spinning speeds until they match their orbital speed. By simulating various initial conditions, we aim to understand the specific paths Pluto and Charon might have taken to reach their current stage. We observe that the tilt of their orbits has a negligible long-term effect, typically stabilizing quickly. In our analysis, we examine a scenario when the orbital size initially increases, leading to an increased orbit and a high eccentricity, a phenomenon attributed to the dissipation of tidal energy.
