在恒星天体物理学中，布居合成技术已经成功地应用了几十年。对于行星来说，它仍然是一个年轻的方法，只是在最近几年才变得重要，因为已知的太阳系外行星的数量迅速增加，以及统计观测约束的相关增长。通过行星人口合成，行星形成和演化的理论可以在这些限制条件下进行测试。在这篇关于行星星族合成的综述中，我们首先简要地列出了关键的观测限制。然后，工作流程的方法和它的两个主要组成部分，即全球端到端模型预测行星系统的性质直接从原行星盘的属性和概率分布，这些初始条件。在文献中的各种人口合成模型的概述。在全球模型中考虑的物理过程的子模型进行了描述：原行星盘的演变，行星的固体和气体的吸积，轨道迁移，N体之间的相互作用，同时增长的原行星。接下来，典型的人口合成结果的形式与最新一代的伯尔尼模型得到的新的合成说明。行星形成轨道，行星在质量距离和半径距离平面的分布，行星质量函数，以及行星半径，半长轴和光度的分布，与基本的物理过程相关联，并与它们的观测对应物进行比较。最后，我们强调了人口合成模型所做的最重要的预测，并讨论了从这些预测中吸取的教训-无论是后来的观测证实和那些拒绝。
In stellar astrophysics, the technique of population synthesis has been successfully used for several decades. For planets, it is in contrast still a young method which only became important in recent years because of the rapid increase of the number of known extrasolar planets, and the associated growth of statistical observational constraints. With planetary population synthesis, the theory of planet formation and evolution can be put to the test against these constraints. In this review of planetary population synthesis, we first briefly list key observational constraints. Then, the work flow in the method and its two main components are presented, namely global end-to-end models that predict planetary system properties directly from protoplanetary disk properties and probability distributions for these initial conditions. An overview of various population synthesis models in the literature is given. The sub-models for the physical processes considered in global models are described: the evolution of the protoplanetary disk, the planets' accretion of solids and gas, orbital migration, and N-body interactions among concurrently growing protoplanets. Next, typical population synthesis results are illustrated in the form of new syntheses obtained with the latest generation of the Bern model. Planetary formation tracks, the distribution of planets in the mass-distance and radius-distance plane, the planetary mass function, and the distributions of planetary radii, semimajor axes, and luminosities are shown, linked to underlying physical processes, and compared with their observational counterparts. We finish by highlighting the most important predictions made by population synthesis models and discuss the lessons learned from these predictions - both those later observationally confirmed and those rejected.
