标题： Ariel Planetary Interiors White Paper

摘要： 近期被采纳的ESA Ariel任务将会测量大量系外行星的大气组成。 这一信息随后将被用来更好地限制行星的整体成分。 尽管行星大气与整体内部成分之间的联系仍在研究之中，但将大气成分与观测到的质量和半径相结合，将会推动系外行星特征分析领域迈向新的台阶，并为银河系内行星的本质提供新的见解。 在这篇白皮书中，我们概述了{\it 阿瑞尔}任务内部工作组正在进行的活动，并列出了在连接行星大气、整体成分和内部结构方面所需的理论发展以及所面临的挑战。 显示英文摘要

摘要： The recently adopted Ariel ESA mission will measure the atmospheric composition of a large number of exoplanets. This information will then be used to better constrain planetary bulk compositions. While the connection between the composition of a planetary atmosphere and the bulk interior is still being investigated, the combination of the atmospheric composition with the measured mass and radius of exoplanets will push the field of exoplanet characterisation to the next level, and provide new insights of the nature of planets in our galaxy. In this white paper, we outline the ongoing activities of the interior working group of the {\it Ariel} mission, and list the desirable theoretical developments as well as the challenges in linking planetary atmospheres, bulk composition and interior structure.
