Project P4: Observational appearance of debris disks

该项目的目标是制定观测战略，以便能够核实关于碎片盘中尘埃的空间结构、基本动力学过程和光学特性的预测。该项目的动机是，现在和在该研究股运行期间，将有新的主要观测台和仪器可供使用，这些观测台和仪器将提供碎片盘观测研究所需的高灵敏度、高角度分辨率能力。它们将使人们能够远远超越过去十年中用斯皮策空间望远镜和赫歇尔空间天文台进行的碎片盘研究的成果。我们将研究多波长，空间分辨观测的潜力，以限制各种尘埃相的空间分布和光学特性，其特征在于它们的大小，化学成分和内部结构（致密/多孔，无定形/结晶，单组分/多层）。此外，还将研究验证研究所其他项目中得出的上述量的预测的可行性（主要是项目P1/P2：盘结构; P5/P6/P7/P8：尘埃性质）。此外，通过向这些小组提供即时反馈，可以优化其调查战略。

The goal of this project is to develop observational strategies that allow the verification of predictions made concerning the spatial structure, underlying dynamical processes, and optical properties of the dust in debris disks. The project is motivated by the fact that now and during the runtime of this Research Unit new major observatories and instruments will become available that will provide high-sensitivity, high-angular resolution capabilities required for observational debris disk studies. They will allow one to go far beyond the legacy of debris disk studies performed with the Spitzer Space Telescope and the Herschel Space Observatory during the past decade. We will investigate the potential of multi-wavelength, spatially resolved observations to constrain the spatial distribution and optical properties of various dust phases, characterized by their size, chemical composition, and internal structure (compact/porous, amorphous/crystalline, single component/multi-layer). Moreover, the feasibility to verify the predictions for the above quantities derived in the other projects of the Research Unit will be investigated (primarily projects P1/P2: disk structure; P5/P6/P7/P8: dust properties). Furthermore, by providing instantaneous feedback to these teams, the strategy of their investigations can be optimized.
