CAREER: Understanding Our Dynamic, Young, Solar Neighborhood

我们可以通过识别似乎一起运动的物体来探索银河系的局部区域。这位研究人员将绘制一张充满活力的、年轻的、太阳能社区的完整地图。在距离太阳约500光年的范围内，有大大小小的恒星、褐矮星和行星组成的家族一起在银河系中运行。有的紧绑，有的松绑，有的分崩离析，有的刚刚形成。该项目的目标是确定这些族是如何形成和演变的。在这样做的过程中，研究小组将解决关于恒星从哪里来以及它们如何到达现在所在位置的基本问题。纽约市的高中教育工作者将作为该项目的一部分。参与者将进一步合作，创造年轻的太阳社区的电影视觉效果。天体物理三维可视化和图像为研究人员提供了洞察力，并激励了普通公众。该项目将图形绘制和聚类算法方法与可视化工具相结合，以创建150个PC Young(1 Gyr)太阳邻域的全面地图，其中包括大质量恒星到棕矮星组件。将公共星表中可用的运动学和自转速度等观测参数结合在一起，将允许绘制核心星团、潮汐尾巴和周围日冕等层次结构的地图。这将使我们能够更好地了解当地恒星在尽可能广泛的质量范围内的形成历史。这些信息将被用来解决一些问题，如恒星形成结构如何随时间演变/消散/溶解，太阳附近年轻星团初始质量函数的均匀程度，以及恒星自转和角动量随时间和恒星质量的演变。科学工作将被纳入一个有凝聚力的教育渠道，其中包括在纽约市一名高中地球科学教师的协助下，为社交媒体和课程整合开发天文馆演示文稿和视频。这份材料将被分发到全球各地的教室和科学中心。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

We can explore our local region of the galaxy by identifying objects that appear to move together. This investigator will produce a complete map of the dynamic, young, solar neighborhood. Within about 500 light years from the Sun, there are large, small, and medium sized families of stars, brown dwarfs, and planets that are moving through the Galaxy together. Some are tightly bound, some loosely bound, some breaking apart, and some are just newly formed. The goal of this project is to determine how these families form and evolve. In so doing, the research team will address fundamental questions about where stars come from and how they arrive at where they are now. New York City high school educators will be included as part of the project. Participants will further collaborate on creating cinematic visuals of the young solar neighborhood. Astrophysical three-dimensional visualizations and imagery provide insights to researchers and inspire the general public. This project will pair graphical plotting and clustering algorithm methods with visualization tools to create a comprehensive map of the 150 pc young (1 Gyr) solar neighborhood inclusive of high mass stars through to brown dwarf components. Coupling observed parameters such as kinematics and rotation rates that are available in public catalogs will permit a mapping of hierarchical structures like core clusters, tidal tails and surrounding coronae. This will enable an improved understanding of the local star formation history across the widest mass range possible. This information will be used to address questions such as how star forming structures evolve/dissipate/dissolve over time, the degree of uniformity of the initial mass function across young clusters in the solar neighborhood, and the evolution of stellar rotation and angular momentum with time and stellar mass. The scientific work will be integrated into a cohesive educational pipeline that includes developing planetarium presentations and videos for social media and course integration, with the assistance of a New York City high school earth science teacher. This material will be distributed to classrooms and science centers across the globe.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
