The goal of project P6 on planetary system dynamics is the dynamical modeling of multiple planetary systems that will be discovered in the course of the CARMENES Survey. Gravitationally interacting planets in a system can tell as much more about their formation and evolution than planets in single systems where those interactions cannot be observed. On top of that the assumption of dynamical stability can even sometimes constrain inclinations and thus individual planet masses in multiple planetary systems.We will carry out dynamical simulations using the SyMBA package in conjunction with a grid search covering a large parameter space in order to assess dynamical stability, the presence of resonances and mutual inclinations among the CARMENES multiple planetary systems. Furthermore, we will also derive ensemble quantities which are tightly linked to the formation and evolution of planetary systems such as the distribution of mutual inclinations or eccentricities. Finally, the analysis of dynamical simulations of multiple or single planetary systems into which potential planets in the habitable zone have been injected can tell us which fraction of systems could in principle harbor planets in the habitable zone, even if those planets do not show up inthe CARMENES data directly. Dynamical simulations will thus help to make full use of the information hidden in the CARMENES data.

行星系统动力学项目P6的目标是多个行星系统的动态建模，这些模型将在Carmenes调查过程中发现。与无法观察到这些相互作用的单个系统中的行星相比，系统中的重力相互作用的行星可以说出它们的形成和进化。最重要的是，动态稳定性的假设甚至有时甚至可以限制倾斜度，从而在多个行星系统中的单个行星质量。我们将使用SYMBA软件包进行动态模拟以及网格搜索涵盖较大的参数空间以评估动态的动态模拟稳定性，在多个行星系统中的共振和相互倾向的存在。此外，我们还将得出与行星系统的形成和演化紧密相关的集成数量，例如相互倾向或偏心率的分布。最后，对多个行星系统或单个行星系统的动态模拟进行分析，注入了可居住区域中的潜在行星可以告诉我们，即使这些行星没有出现在居住区中的哪一部分可能是居住区的行星，即使在Carmenes数据直接。因此，动态模拟将有助于充分利用隐藏在卡门群数据中的信息。
