This award supports the analysis of photometric observations of over 100 star clusters using the Apache Point Observatory Galactic Evolution Experiment (APOGEE). The PI will 1) provide a uniform calculation of star-cluster ages and distance using uniform photometry from large surveys, 2) build a high precision dynamical sample of open cluster tracers, and 3) determine the Galactic disk abundance gradients using a large open cluster sample.The APOGEE survey will provide a picture of the disk of the Milky Way galaxy that is unrivaled in scope, richness, and detail. In turn, this research will provide critical information for our understanding of the Milky Way in a fully cosmological context. The PI will also make the APOGEE-derived dataset available to the community, as well as train undergraduate and graduate students at Texas Christian University.

该奖项支持使用Apache Point Point Garactator Galactic Evolution Evolution Evolutions（Apogee）对超过100星簇的光度观测分析。 PI将1）使用大型调查中均匀的光度法提供统一的恒星群体年龄和距离计算，2）使用大型开放式群集样品确定一个高精度的动力学样本，以及3）确定银河系磁盘的丰度梯度。反过来，这项研究将为我们在完全宇宙学的背景下对银河系的理解提供关键信息。 PI还将使社区访问的数据集以及德克萨斯基督教大学的培训本科生和研究生。
