第10031章 表面与内部

Chapter 10031. Surfaces and Interiors

Lena Noack, Caroline Dorn, Philipp Baumeister

AI总结:

该研究梳理了系外行星(超级地球、亚海王星)内部与表面演化研究的进展,介绍了新兴的系外行星地球科学领域,并指出JWST与ELT将助力验证相关大气多样性理论预测。

摘要:

自发现首批太阳系外低质量行星以来的15年间,人类对(超级)地球与亚海王星系外行星的多样性认知取得了巨大进展。学界尤其针对系外行星内部结构对其表面演化(含大气演化)的影响展开了细致研究。早期研究仅以质量和半径为核心观测量,开展行星表征(包括潜在内部结构)相关研究。与此同时,系外行星地球科学这一新领域已然兴起,它将行星与其恒星环境相关联,并把内部化学与动力学过程同表面状态、大气组成耦合起来。JWST(詹姆斯·韦布空间望远镜)与ELT(极大望远镜)开启的大气表征新时代,将能够验证这些基于内部结构、演化及排气模型的大气多样性理论预测。

英文摘要:

In the last 15 years, since the discovery of the first low-mass planets beyond the solar system, there has been tremendous progress in understanding the diversity of (super-)Earth and sub-Neptune exoplanets. Especially the influence of the planetary interior on the surface evolution (including the atmosphere) of exoplanets has been studied in detail. The first studies focused on the characterization of planets, including their potential interior structure, using as key observables only mass and radius. Meanwhile, a new field of geosciences of exoplanets has emerged, linking the planet to its stellar environment, and by coupling interior chemistry and dynamics to surface regimes and atmospheric compositions. The new era of atmospheric characterization by JWST as well as the ELT will allow testing of these theoretical predictions of atmospheric diversity based on interior structure, evolution, and outgassing models.
