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.

马修·德·福里奥 (Matthew De Furio) 获得美国国家科学基金会天文学和天体物理学奖学金，在德克萨斯大学奥斯汀分校开展研究和教育项目。 De Furio 将观测四个不同恒星形成区域（从低密度未束缚区域到高密度束缚区域）内的数百颗恒星，以识别双星和高阶多重系统。这项工作的结果将有助于我们了解恒星形成过程并探索恒星诞生环境的影响。 De Furio 还将使用望远镜和天文馆等常见大学资源，设计和实施一项专门针对智障儿童和成人的教育计划。这项工作将使用盖亚天文台提供的地面和空间成像来表征两个低密度 OB 协会、一个高密度束缚星团和一个质量为 0.3 M⊙ 的主恒星的非常年轻的嵌入区域内的多重性。凭借探测超过 10 个天文单位的伴星的能力，该项目将：1) 探讨动力学对多个系统的形成和保留的影响，2) 探索哪些类型的恒星形成区域对银河场种群有重大贡献，以及 3) 对我们对多恒星形成理论作为初级质量和轨道间隔的函数的理解施加根本限制。该奖项反映了 NSF 的法定使命，并被认为值得通过以下方式获得支持： 使用基金会的智力价值和更广泛的影响审查标准进行评估。
