AI 中文摘要
凌日时间变化（TTV）方法是确认、探测和表征系外行星系统的关键途径。本综述讨论了从凌日观测中探测TTV的方法，以及TTV的起源，其主要归因于与扰动行星（无论是否凌日）的引力相互作用。此外，本工作详细介绍了在贝叶斯框架内采用准全局和局部优化算法来推导行星参数的方法。通过分析TTV，可以推断出行星轨道参数和动力学特性，为系统形成与演化提供宝贵见解。本综述还探讨了共振和稳定性在塑造这些系统中的作用，以及影响质量测定的敏感性偏差。比较分析突显了TTV系统独特的种群贡献。TTV为研究行星系统的动力学和物理特性提供了窗口，增进了我们对其多样性和稳定性的理解。
英文摘要
The transit timing variation (TTV) method is a key approach to the confirmation, detection, and characterisation of exoplanetary systems. This review discusses the detection of TTVs from transit observations and the origins of TTVs, mainly due to gravitational interactions with perturbing planets, whether transiting or not. Additionally, this work details methodologies for deriving planetary parameters, employing quasi-global and local optimisation algorithms within a Bayesian framework. By analysing TTVs, planetary orbital parameters and dynamical properties can be inferred, providing valuable insights into system formation and evolution. The role of resonances and stability in shaping these systems is reviewed, along with sensitivity biases that influence mass determination. Comparative analyses highlight the unique demographic contributions of TTV systems. TTVs offer a window into the dynamical and physical properties of planetary systems, advancing our understanding of their diversity and stability.
