Hundreds of extra-solar planets have been found around other stars. Many are systems with several planets orbiting a single star, partly with outer and/or inner debris disks. These planetary systems exhibit a large variety, and their organization can differ much for the solar system architecture. Planetary systems are found around single, binary, and triple stars; some include planets in resonant orbits, planets at very small (below one AU, detected by radial velocity and/or transit) and very large (tens to more than 100 AU, detected by direct imaging) separation from the host star. Here, we propose to search of outer planets in a sample of stars by direct imaging with Adaptive Optics. The sample includes selected stars with debris disks, in some of which one or more inner planets are already known. In a parallel project, systems will be searched for inner planets. Another accompanying project will provide a theoretical analysis of the complete planetary systems. Thus the entire Packet Proposal aims to study the architecture of full planetary systems by both observations and theory.

在其他恒星周围发现了数百颗太阳系外行星。许多系统有几颗行星围绕一颗星星运行，部分有外部和/或内部的碎片盘。这些行星系统表现出很大的多样性，它们的组织可以根据太阳系的结构而有所不同。行星系统存在于单星、双星和三星周围;有些行星在共振轨道上，有些行星与主星星的距离很小（低于一个Au，通过径向速度和/或凌日探测到），有些行星与主恒星的距离很大（数十到超过100个Au，通过直接成像探测到）。在这里，我们建议搜索外行星的恒星样本直接成像与自适应光学。样本包括选定的具有碎片盘的恒星，其中一些已经知道有一个或多个内行星。在一个平行的项目中，将搜索系统的内行星。另一个伴随项目将提供完整的行星系统的理论分析。因此，整个包建议旨在通过观测和理论来研究完整行星系统的结构。
