摘要
研究系外行星系统中的行星相互作用有助于理解行星形成与演化，为理解我们自己的太阳系提供必要的背景。我们结合光谱学、传递光度学、传递时序变化和测距学，对 TOI-201 系统进行表征。该共通透过的系统由一颗超地球、温暖木星和一颗质量巨大的伴星组成，其轨道周期分别为 5.8、53 和 2900 天。我们进行动力学模拟，研究该系统的过去与未来。von-Zeipel-Kozai-Lidov 振荡最有可能解释外伴星的高轨道偏心率，而行星-行星散射则是可能但不太可能的替代方案。由于行星之间存在非零的互斜倾角，该系统在非常短的 timescales 上可见地演化，当前的共通透过配置将在 200 年内结束。
