摘要

系外行星系统表现出多种多样的结构,可以用不同的形成和动态演化过程来解释。精确的轨道监测是精确约束其轨道参数和动力学参数的必要条件。尽管在了解系外行星系统的结构和动力学特性方面取得了重大的观测和理论进展,但仍有许多悬而未决的问题。本文旨在简要回顾系外行星系统轨道和动力学研究中当前面临的一些挑战,以及未来提高我们知识的一些前景。来自几种技术的联合数据分析为越来越多的系外行星系统样本提供了轨道和质量的精确测量,包括近轨道和宽轨道,以及不同的进化阶段。在有星周圆盘的恒星周围发现的年轻行星的样本也在增加,这使得对行星及其出生地环境的同时研究成为可能。这些分析将随着地面和太空正在进行的和未来的设施而扩大,允许对系外行星的形成、演化和大气模型进行详细的测试。此外,这些详细的分析可能会提供发现系外行星系统缺失的组成部分的可能性,例如系外卫星,甚至发现新的奇异结构,例如共轨道行星。除了揭示行星系统的结构外,轨道参数和恒星特性的精确测量——结合更现实的潮汐相互作用模型和将这些模型集成到N体代码中——将改进对近距离轨道上成熟系外行星系统过去历史的推断。这些改进将使我们更好地了解行星的形成和演化,将太阳系置于背景中。

Workshop Summary: Exoplanet Orbits and Dynamics
Abstract Exoplanetary systems show a wide variety of architectures, which can be explained by different formation and dynamical evolution processes. Precise orbital monitoring is mandatory to accurately constrain their orbital and dynamical parameters. Although major observational and theoretical advances have been made in understanding the architecture and dynamical properties of exoplanetary systems, many outstanding questions remain. This paper aims to give a brief review of a few current challenges in orbital and dynamical studies of exoplanetary systems and a few future prospects for improving our knowledge. Joint data analyses from several techniques are providing precise measurements of orbits and masses for a growing sample of exoplanetary systems, both with close-in orbits and with wide orbits, as well as different evolutionary stages. The sample of young planets detected around stars with circumstellar disks is also growing, allowing for simultaneous studies of planets and their birthplace environments. These analyses will expand with ongoing and future facilities from both ground and space, allowing for detailed tests of formation, evolution, and atmospheric models of exoplanets. Moreover, these detailed analyses may offer the possibility of finding missing components of exoplanetary systems, such as exomoons, or even finding new exotic configurations such as co-orbital planets. In addition to unveiling the architecture of planetary systems, precise measurements of orbital parameters and stellar properties—in combination with more realistic models for tidal interactions and the integration of such models in N -body codes—will improve the inference of the past history of mature exoplanetary systems in close-in orbits. These improvements will allow a better understanding of planetary formation and evolution, placing the solar system in context.
