随着系外行星探测技术的发展，观测上已发现了大量的热木星系统，这些观测数据为深入开展热木星的形成机制研究提供了良好的观测样本。但是迄今为止，热木星的起源尚存在着激烈的争论，是热木星研究方向的热点课题。本项目拟采用数值模拟和理论分析方法，探索系统中潜在的暖木星伴星和恒星的自转特性对热木星形成过程的影响。热木星的动力学演化过程主要考虑伴星的引力摄动，恒星的潮汐和相对论修正等。通过本项目的执行，可以获得行星伴星和恒星的自转特性对热木星形成的影响，揭示热木星可能的形成机制，解释热木星在观测上的半长轴分布和暖木星伴星的存在几率。这些研究结果将有助于进一步完善热木星形成理论，同时为将来的观测提供理论依据。

With the development of exoplanetary observation techniques, lots of hot Jupiters are detected in recent years. These observation data provide significant foundation to carry out intensive research on the physical characteristics and formation mechanism of hot Jupiters. However, the topic on the origin of hot Jupiters is still in dispute without any final conclusions, and becomes a hot issue in the field of exoplanetary science. With the combination of theoretical analysis and numerical simulations, we are going to explore the effects on the formation of hot Jupiters caused by a potential warm Jupiter companion and stellar rotation features. Gravitational perturbations induced by planetary companions, tidal effects as well as relativistic correction will be taken into consideration in the dynamical evolution of hot Jupiters. The main goal of this project is a) to reveal the relations between hot Jupiters formation and potential planetary companion as well as features of Stellar rotation, b) to investigate possible formation mechanism of hot Jupiters, c) to interpret the possibility of existence and distribution of semi-major axis of hot Jupiters detected through multiple ways of observation. Results of our study will help to complete formation theory of hot Jupiters and provide a theoretical basis for future observations.
