Project P4: Observational appearance of debris disks

该项目的目标是制定观测策略，以验证有关碎片盘中尘埃的空间结构、潜在动力过程和光学特性的预测。该项目的动机是，现在和在本研究股运行期间，将会有新的主要天文台和仪器，提供观测碎片盘研究所需的高灵敏度、高角度分辨率能力。在过去的十年里，他们将允许人们远远超越斯皮策太空望远镜和赫歇尔空间天文台所做的碎片盘研究的遗产。我们将研究多波长、空间分辨观测的潜力，以约束各种尘埃相的空间分布和光学性质，其特征是它们的大小、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，还将调查研究股其他项目（主要是项目P1/P2：磁盘结构；项目P5/P6/P7/P8：粉尘特性）中对上述数量的预测是否可行。此外，通过向这些团队提供即时反馈，可以优化他们的调查策略。

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.
