原行星盘的化学演化

The Chemical Evolution of Protoplanetary Disks

Edwin A. Bergin

摘要:

行星的起源,或许还有生命本身,都与行星形成的化学过程有着内在的联系。在本章中,我们将尝试从几十年来太阳系研究中获得的知识的角度,结合我们对太阳系外原行星盘的快速增长的知识,探索行星形成盘的化学。我们的目的不是提供一个全面的文献调查,而是目前的化学和物理工具,用于探索化学演化的最早阶段的行星形成。我们包括从我们的太阳系和太阳系外的磁盘,热力学平衡和化学动力学的观测约束的讨论,和物理处方的各个重要方面(X-射线/紫外线照射,热结构,分子吸附/解吸,.)在当前的模型中使用。这一章是针对年轻研究人员的。

英文摘要:

The origins of planets, and perhaps life itself, is intrinsically linked to the chemistry of planet formation. In this chapter we will attempt to explore the chemistry of planet-forming disks from the perspective of knowledge gained from decades of solar system study, combined with our rapidly growing knowledge of extra-solar protoplanetary disks. Our aim is not to provide a comprehensive survey of the literature, but rather to present the chemical and physical tools that are used to explore chemical evolution during the earliest stages of planet formation. We include a discussion of observational constraints from our solar system and extra-solar disks, thermodynamic equilibrium and chemical kinetics, and the physical prescriptions for various important aspects (X-ray/UV irradiation, thermal structure, molecular adsorption/desorption, ..) that are used in current models. The chapter is aimed for young researchers.
