论文摘要
我们描述了一种快速，近似方法，以在数值模拟中表征卫星围绕卫星的轨道。一个目标是区分自由偏心率 - 卫星相对于动态较酷轨道的随机运动与由中央二元时间变化的引力电位驱动的振荡模式。我们使用Kepler-16，Kepler-47和Pluto-Charon系统评估该方法的性能。然后，我们将该方法应用于轨道阻尼在环境环境中的模拟，从而解决了足够慢以促进合并和生长的小体之间的相对速度。这些结果说明了动态冷却如何为在恒星二进制的二进制二进制二进制二进制二进制二进制行星周围形成类似tatooine的行星奠定基础。
We describe a fast, approximate method to characterize the orbits of satellites around a central binary in numerical simulations. A goal is to distinguish the free eccentricity -- random motion of a satellite relative to a dynamically cool orbit -- from oscillatory modes driven by the central binary's time-varying gravitational potential. We assess the performance of the method using the Kepler-16, Kepler-47, and Pluto-Charon systems. We then apply the method to a simulation of orbital damping in a circumbinary environment, resolving relative speeds between small bodies that are slow enough to promote mergers and growth. These results illustrate how dynamical cooling can set the stage for the formation of Tatooine-like planets around stellar binaries and the small moons around the Pluto-Charon binary planet.
