论文摘要

渐进的天文学特征是构成行星磁盘和岩石系外行星的渐进式表征,强调了增加跨学科的努力,以了解统一的图片中陆地世界的出生和生命周期。在这里,我们回顾了主要的地球物理和地球化学过程,这些过程塑造了行星形成和早期进化过程中岩石行星及其前体行星的演变,以及它们如何映射到天体物理时间表和行星生长的变化积聚环境中。生长的原生膜在热,成分和结构状态下的耦合核心助向大气系统的演变与一阶不同,并最终塑造了关键的行星特征,这些行星特征可以辨别出具有克莱门特表面条件的行星与没有的行星。试图调查岩石系外行星的天文运动将需要在实验室表征行星材料以及行星进化的时间和空间分辨的理论模型方面取得重大进展,以将行星科学扩展到太阳系之外,并限制我们自己的可居住世界的起源和频率。

Progressive astronomical characterization of planet-forming disks and rocky exoplanets highlight the need for increasing interdisciplinary efforts to understand the birth and life cycle of terrestrial worlds in a unified picture. Here, we review major geophysical and geochemical processes that shape the evolution of rocky planets and their precursor planetesimals during planetary formation and early evolution, and how these map onto the astrophysical timeline and varying accretion environments of planetary growth. The evolution of the coupled core-mantle-atmosphere system of growing protoplanets diverges in thermal, compositional, and structural states to first order, and ultimately shapes key planetary characteristics that can discern planets harboring clement surface conditions from those that do not. Astronomical campaigns seeking to investigate rocky exoplanets will require significant advances in laboratory characterization of planetary materials and time- and spatially-resolved theoretical models of planetary evolution, to extend planetary science beyond the Solar System and constrain the origins and frequency of habitable worlds like our own.
