The goal of this project is to derive observable quantities which allow to constrain the existence and major parameters of giant protoplanets as well as the physical conditions and processes during their formation in young circumstellar disks. Based on our selected preparatory studies which demonstrate the feasibility of this project we will consider a broad range of planetary and stellar masses and circumstellar disk properties as suggested by exoplanet observations and planet population synthesis studies. This is a timely project as during the proposed funding period large ground-based and space observatories and instruments will become available which are expected to provide the spatial resolution, sensitivity, and dynamic range needed to perform these observations. Using our state-of-the-art 3D magneto-hydrodynamical (MHD) and 3D radiative transfer codes we aim at providing the basis necessary for the observational verification of theoretical models of the late stages of giant planet formation.

该项目的目标是推导出可观测的数量，这些数量可以限制巨型原行星的存在和主要参数，以及它们在年轻的星周盘中形成的物理条件和过程。根据我们选定的证明该项目可行性的预备研究，我们将考虑系外行星观测和行星群综合研究所建议的广泛的行星和恒星质量以及星周盘特性。这是一个及时的项目，因为在拟议供资期间，大型地面和空间观测台和仪器将可供使用，预计将提供进行这些观测所需的空间分辨率、灵敏度和动态范围。使用我们最先进的3D磁流体动力学（MHD）和3D辐射传输代码，我们的目标是提供必要的观测验证巨行星形成的后期阶段的理论模型的基础。
