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.

该奖项支持使用阿帕奇点天文台星系演化实验(APOEE)对100多个星团的光度观测进行分析。PI将1)使用来自大型测量的统一测光技术提供统一的星团年龄和距离计算，2)建立开放星团示踪器的高精度动态样本，以及3)使用大的开放星团样本确定银盘丰度梯度。远地点调查将提供在范围、丰富度和细节上无与伦比的银河系盘状图像。反过来，这项研究将为我们在完全宇宙学的背景下理解银河系提供关键信息。PI还将向社区提供来自远地点的数据集，并培训德克萨斯基督教大学的本科生和研究生。
