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.

我们可以通过识别似乎一起移动的对象来探索银河系的局部区域。 该研究人员将制作一个动态，年轻的太阳能社区的完整地图。 在距离太阳约500光年之内，有一起穿过银河系的恒星，棕色矮人和行星的大型，中小型和中等大小的家族。有些是紧密的绑定，有些松散地绑定，有些分裂，有些只是新形成的。 该项目的目的是确定这些家庭如何形成和发展。 这样一来，研究团队将解决有关星星的来源以及它们如何到达现在的位置的基本问题。 纽约市高中教育者将被包括在该项目中。参与者将进一步合作创建年轻太阳能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见解，并激发了公众。该项目将将图形绘图和聚类算法方法与可视化工具相结合，以创建150 pc Young（1 Gyr）太阳能街区的全面地图，包括高质量恒星，直至棕色矮人组件。耦合观察到的参数，例如在公共目录中可用的运动学和旋转速率，将允许绘制诸如核心簇，潮汐尾巴和周围冠状动脉等层次结构的映射。 这将使人们能够在最广泛的质量范围内对本地恒星形成历史有了深刻的了解。 这些信息将用于解决问题，例如恒星形成结构如何随着时间的流逝而演变/消散/溶解，跨太阳邻居中年轻群集的初始质量功能的均匀程度，以及随时间和恒星质量的恒星旋转和角动量的演变。科学工作将融入一个具有凝聚力的教育管道中，其中包括在纽约市高中地球科学老师的帮助下开发了天文馆演示和社交媒体和课程整合的视频。 该材料将分发给全球的教室和科学中心。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的审查标准，被视为值得通过评估的支持。
