Matthew De Furio is awarded an NSF Astronomy and Astrophysics Fellowship to carry out a program of research and education at the University of Texas at Austin. De Furio will observe hundreds of stars within four different star-forming regions (from low-density unbound to high-density bound regions) to identify binary and higher order multiple systems. Results from this work will inform our understanding of the star formation process and explore effects from the stellar birth environment. De Furio will also design and implement an educational program devoted to children and adults with intellectual disabilities using common university resources like telescopes and planetariums.This work will characterize the multiplicity within two low-density OB associations, one high-density bound cluster, and one very young embedded region for primary stars with masses 0.3 M⊙ using ground and space based imaging informed by the Gaia observatory. With the ability to detect companions beyond 10 au, this project will: 1) probe the impact of dynamics on the formation and retention of multiple systems, 2) explore which types of star-forming regions contribute significantly to the Galactic field population, and 3) place fundamental constraints on our understanding of multiple star formation theory as a function of primary mass and orbital separation.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.

Matthew de Furio被授予NSF天文学和天体物理学奖学金，以在德克萨斯大学奥斯汀分校进行研究和教育计划。 De Furio将在四个不同的恒星形成区域（从低密度未结合到高密度结合区域）中观察数百个恒星，以识别二元和高阶多个系统。这项工作的结果将为我们对恒星形成过程的理解提供信息，并探索恒星生日环境的影响。 De Furio还将设计和实施一个教育计划，该计划使用远程望远镜和天文馆（如望远镜和天文馆）为儿童和成年人提供智力残障的儿童和成人。这项工作将表征两个低密度OB关联中的多重性，一个高密度绑定的集群，一个非常年轻的型号，用于使用基于地面和太空的质量的质量的原始恒星，并具有质量为0.3 M的原始星星。该项目能够检测到10 au以上的伴侣的能力，将：1）探测动态对多个系统的形成和保留的影响，2）探索哪种类型的恒星形成区域对我们对多星形和奥尔布尔分离的功能的理解，对我们对多星形和奥尔布尔的奖励的理解，将基本限制对我们对多个质量和奥尔布尔的奖励的理解产生重大约束。使用基金会的智力优点和更广泛的影响评估标准进行评估。
