Star and planet formation is one of the most active and exciting research areas of modern astrophysics. Many of the open questions in this field are related to the structure and physics of the innermost regions of protoplanetary disks, where material is transported onto the forming star, ejected in powerful jets & outflows, or accreted onto newly-formed planets. However, most of the aforementioned processes take place on astronomical unit-scales very close to the star, which has prevented a direct investigation with imaging observations so far. The aim of this project is to employ the new opportunities provided by infrared and sub-millimeter interferometry in order to explore the terrestrial planet-forming zone in protoplanetary disks for the first time with direct imaging. The obtained images will reveal the fundamental inner disk structure and allow us to search for planet-related disk surface structures, such as tidally cleared gaps or the hot accretion region around young, embedded protoplanets. Combining interferometric observations at infrared and sub-millimeter wavelengths will allow us to determine the temperature & density distribution and dust composition in the inner disk. This approach will result in an unprecedented global view on the structure and physical processes in protoplanetary disks and help us to understand how planets are forming and how they interact with the disk material during their early evolution.

恒星和行星形成是现代天体物理学最活跃，最令人兴奋的研究领域之一。该领域中的许多空旷问题与原月球磁盘最内向区域的结构和物理学有关，该磁盘将材料运输到形成恒星上，以强大的喷气式飞机和流出弹出，或被吸收到新成型的行星上。但是，上述大多数过程都在非常接近恒星的天文单位尺度上进行，这阻止了到目前为止对成像观测的直接研究。该项目的目的是利用红外和亚毫米干涉仪提供的新机会，以便首次使用直接成像探索原行星磁盘中的陆地形成区域。所获得的图像将揭示基本的内部磁盘结构，并使我们能够搜索与行星相关的磁盘表面结构，例如潮汐清除的间隙或周围的年轻，嵌入的原始球星的热积聚区域。在红外和亚毫米波长处的干涉测量值结合度将使我们能够确定内部磁盘中的温度和密度分布和灰尘组成。这种方法将导致对原星盘的结构和物理过程的前所未有的全球观点，并帮助我们了解行星的形成方式以及它们在早期演变过程中如何与磁盘材料相互作用。
