This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). Dr. Rupali Chandar (University of Toledo) will use space- and ground-based data to make a detailed study of the properties of star clusters in 20 star-forming galaxies, covering most types and environments found in the nearby universe. This program will explore a new hypothesis, based on preliminary results from two very different galaxies, that the basic physical processes of star cluster formation and disruption are essentially the same, whether they operate on open, super-star, or globular star clusters, and regardless of the type of galaxy or environment in which they form. If correct, this picture revises some long-held beliefs about the formation and disruption of star clusters. Regardless of the outcome, this research will take a major step forward in understanding the physics of star and cluster formation, the life cycle of clusters, and the stellar content within galaxies.Dr. Chandar will make the extensive set of reduced, integrated-light spectra of star clusters in nearby galaxies which will result from this research available to the public in order to enable many follow-up projects. As part of this program, Dr. Chandar will also develop two new education initiatives: (1) "Girls in Science", an outreach event aimed at middle school girls, will incorporate data from the research portion of this proposal into hands-on activities, and (2) "Beyond the Solar System", a new teacher training initiative focused on topics related to this proposal and aligned with State and Federal science standards.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。Rupali Musharar博士（托莱多大学）将利用空间和地面数据，详细研究20个恒星形成星系中的星星团的性质，其中包括在附近宇宙中发现的大多数类型和环境。 该计划将探索一个新的假设，基于两个非常不同的星系的初步结果，即星星集群形成和破坏的基本物理过程本质上是相同的，无论它们是在开放的超级星星还是球状星星集群上运行，也不管它们形成的星系或环境的类型。如果是正确的，这张图片修正了一些长期以来关于星星团形成和分裂的信念。无论结果如何，这项研究将在理解星星和星系团形成的物理学、星系团的生命周期以及星系中恒星的含量方面向前迈出重要一步。Dr. Barnar将向公众提供这项研究的结果，即附近星系中星星团的大量简化、综合光谱，以使许多后续项目得以进行。作为该方案的一部分，Dr. Eschar还将制定两项新的教育倡议：（1）“科学中的女孩”，这是一项针对中学女孩的推广活动，将把本提案研究部分的数据纳入实践活动，以及（2）“超越太阳系”，这是一项新的教师培训倡议，重点是与本提案有关的主题，并与州和联邦科学标准保持一致。
