Dr. Eugene Chiang of the University of California (Berkeley) will undertake a three year study of the various forces that affect the growth and destruction of dust and small bodies in circumstellar debris disks. These forces include collisions, stellar radiation, and the gravitational perturbation from planets. The work will also elucidate how early planets and destructive collisions scatter or eliminate dust from the debris disks. The main goal will be to infer the masses and orbits responsible for the variety of structures seen in high-resolution images of these disks. The project will address many issues about the formation of the Kuiper Belt of dust and cometary bodies in our own solar system and may be useful for the interpretation of future observations, like those from the NSF-supported Gemini Planet Imager survey. The principal investigator and his group also plan a number of public outreach activities to illustrate the processes of planet formation.

加州大学伯克利分校的Eugene Chiang博士将进行一项为期三年的研究，研究影响星际碎片圆盘中尘埃和小天体生长和破坏的各种力量。这些作用力包括碰撞、恒星辐射和来自行星的引力扰动。这项工作还将阐明早期行星和破坏性碰撞是如何分散或消除碎片盘上的尘埃的。主要目标将是推断在这些圆盘的高分辨率图像中所看到的各种结构的质量和轨道。该项目将解决许多关于我们太阳系中尘埃和彗体的柯伊伯带形成的问题，并可能有助于解释未来的观测结果，比如美国国家科学基金会支持的双子座行星成像仪调查。首席调查员和他的小组还计划开展一些公共宣传活动，以说明行星形成的过程。
