Measuring Age-Dependent Galactic Abundance Gradients with APOGEE

该奖项支持使用Apache Point Observatory Galactic Evolution Experiment（APOGEE）对100多个星星集群进行光度观测分析。PI将1）使用大型巡天的统一测光提供星团年龄和距离的统一计算，2）建立高精度的疏散星团示踪剂动力学样本，3）使用大型疏散星团样本确定银河系盘丰度梯度。APOGEE巡天将提供银河系盘在范围、丰富性和细节方面无与伦比的图片。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APOGEE衍生的数据集，并培训德克萨斯基督教大学的本科生和研究生。

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.
