Hundreds of planetary systems have been discovered around other stars. They come in a bewildering variety of shapes and sizes, and there is emerging evidence for their complexity. Yet their detailed architecture remains largely unknown even in the best-studied cases. The present project deals with “full” planetary systems which contain, apart the central star and one or several planets, also one or more dust disks (indicative of planetesimal belts). A handful of them are known, and more can be found with the help of accompanying projects that will search for inner and outer planets. The main goal of this project is to perform a comprehensive, coherent theoretical analysis of several selected “full” planetary systems. It will include constraining the system age, properties of the central star, masses and orbits of the planets, key parameters of the planetesimal belts; finding out the origin and chemical composition of dust; a dynamical stability study of the planets of the belts against perturbations by planets; and other issues. We will also attempt to roughly reconstruct possible formation scenarios and evolutionary paths of the systems. This will result in a synthetic view of several complex planetary systems, uncover their similarities and dissimilarities with the solar system, and finally, contribute to a better understanding of how planetary systems form and evolve.

在其他恒星周围已经发现了数百个行星系统。它们有着令人眼花缭乱的各种形状和大小，并且有越来越多的证据表明它们的复杂性。然而，即使在最好的研究案例中，它们的详细结构在很大程度上仍然是未知的。本项目涉及“完整的”行星系统，除了中心星星和一个或几个行星外，还包含一个或多个尘埃盘（指示微行星带）。其中一些是已知的，更多的可以在伴随的项目的帮助下找到，这些项目将搜索内部和外部行星。该项目的主要目标是对几个选定的“完整”行星系统进行全面、连贯的理论分析。它将包括限制系统年龄、中心星星的性质、行星的质量和轨道、微行星带的关键参数;查明尘埃的来源和化学成分;对微行星带的行星进行动力学稳定性研究，以防止行星的扰动;以及其他问题。我们还将尝试大致重建可能的形成场景和系统的演化路径。这将导致几个复杂的行星系统的综合视图，揭示它们与太阳系的相似性和差异性，并最终有助于更好地了解行星系统如何形成和演化。
