AST 0407232TrillingThe Kuiper Belt, a ring of debris and dust outside the planetary realm of our Solar System,is the last, most pristine record of the processes of planetary accretion in our Solar System.Dr. David Trilling and his collaborator Dr. Marc Buie will study the Kuiper Belt and its residents, Kuiper Belt Objects (KBOs), to constrain the timescale of accretion in the outer Solar System. Trilling and Buie both participate in the ongoing, large-scale Deep Ecliptic Survey (DES) for KBOs and will use the DES database as the backbone of their science endeavors. The tasks to be carried out are as follows. Trilling will make new observations in the DES program. Trilling and Buie will also carry out a comprehensive photometry program that will be used to calibrate the DES catalog. Both of these observing tasks will make extensive use of telescopes in Arizona and Chile. Lastly, Trilling and Buie will carry out completeness experiments on the DES catalog. These three tasks prepare the way for scientific analysis of the Kuiper Belt using the 500 DES KBOs. The first step of the science analysis will be to carry out a statistical study of the DES data in combination with other surveys' data to derive, with strong confidence, the differential sky density of KBOs. This mathematical expression can be directly related to accretion timescales through theoretical models to provide a tight constraint on the duration of accretion in the Kuiper Belt. Lastly, combining the DES dataset with newly available KBO albedo information from the Space Infrared Telescope Facility allows a true KBO size distribution to be derived for the first time. The intellectual merit of these technical tasks and science goals lies in the quest to understandhow the outer Solar System formed and evolved. The results derived here will be crucially important in constraining and driving the next generation of outer Solar System accretion models. These models have impact beyond the Kuiper Belt, as planets in the Solar System (and beyond) underwent accretion as part of their formation processes. This program will have a broader impact in the community primarily through participation in the University of Arizona Space Grant program. Through the Space Grant program, Trilling will recruit one undergraduate research intern per year from among the diverse pool of applications. This series of students will have specific research tasks, including participating in observing runs. Trilling will also participate in Space Grant's Science Speakers program to present science results in classrooms and to the general public. Such a program uniquely allows bringing knowledge to communities of racial, ethnic, and economic diversity. Lastly, in addition to public outreach, this research program will produce an extensive photometric catalog, which will be widely available, and will calibrate the large DES archive, which will also be available for use in various other scientific projects from Solar System science to cosmology.

AST 0407232 Trilling Trillthe Kuiper带是我们太阳能系统的行星境外碎屑和灰尘的环，是太阳系中行星积聚过程的最后一个，最原始的记录。 David Trilling和他的合作者Marc Buie博士将研究Kuiper Belt及其居民Kuiper Belt物体（KBOS），以限制外部太阳能系统中积聚的时间尺度。 TRILLING和BUIE都参加了KBO的正在进行的大规模的深层黄道调查（DES），并将使用DES数据库作为其科学努力的骨干。要执行的任务如下。 TRILLING将在DES程序中进行新的观察。 TRILLING和BUIE还将执行一项全面的光度法程序，该程序将用于校准DES目录。这两个观察任务都将在亚利桑那州和智利广泛使用望远镜。最后，Trilling和Buie将在DES目录上进行完整的实验。这三个任务为使用500 des kbos的kuiper带科学分析准备了道路。科学分析的第一步将是对DES数据进行统计研究，并结合其他调查的数据，以强烈的自信，KBOS的差异天空密度得出。这种数学表达可以通过理论模型直接与增生时间尺度相关，从而对Kuiper带的积聚持续时间进行严格限制。最后，将DES数据集与来自太空红外望远镜设施的新近可用的KBO反照率信息相结合，可以首次得出真正的KBO大小分布。这些技术任务和科学目标的智力优点在于追求了解如何形成和发展的外部太阳系。此处得出的结果对于限制和推动下一代太阳系积聚模型至关重要。这些模型超出了Kuiper带，作为太阳系（及以后）的行星作为其编队过程的一部分进行了积聚。该计划将主要通过参加亚利桑那大学太空赠款计划，对社区产生更大的影响。通过太空赠款计划，Trilling将每年从各种应用程序中招募一名本科研究实习生。这一系列学生将执行特定的研究任务，包括参与观察跑步。 TRILLING还将参加Space Grant的科学演讲者计划，以在教室和公众中呈现科学成果。这样的计划独特地允许将知识带入种族，种族和经济多样性的社区。最后，除了公开外展外，该研究计划还将生成广泛的光度目录，该目录将广泛使用，并将校准大型DES档案，该目录也将用于从太阳系科学到宇宙学的其他各种科学项目中使用。
