This correlation results from the following two processes: On one hand the temporal evolution of the gas content of the protoplanetary disk causes migration of the planets and therefore determines the orbital architecture of the system. On the other hand the composition of the planets depends on the structure and composition of the disk of solids itself related to the gas content of the disk and the solid-to-gas ratio in the disk. This latter quantity is finally correlated with the stellar metallicity. The goal of ArchiCHESS is to observe multi-planetary systems to constrain their architecture (using architecture coefficients of Mishra et al. 2023) and relate this to the water fractions of the planets as well as to the metallicity of the central star.

项目标题：轴1——探究轨道架构-行星组成-金属丰度关联（ArchiCHESS）
项目摘要：行星形成模型预言，行星系统的轨道架构、行星组成与中央恒星的金属丰度之间存在关联。该关联源自如下两个过程：其一，原行星盘气体含量的时间演化会引发行星迁移，进而决定系统的轨道架构；其二，行星的组成取决于固体盘的结构与成分，而固体盘的结构和成分与盘内气体含量及盘内固气比相关，这一物理量最终与恒星金属丰度存在关联。ArchiCHESS项目的目标是对多行星系统开展观测，利用米什拉等（Mishra et al.）2023年提出的架构系数约束其轨道架构，并将该架构与行星的水丰度以及中央恒星的金属丰度联系起来。
