Dr. Rosemary Wyse at the Johns Hopkins University will use this award to continue her investigation of the present day kinematics and distribution of chemical elements of the stars of our Milky Way Galaxy. Over 2000 stellar spectra have been obtained with support from a prior NSF grant. Observations will continue, but the emphasis will shift to the analysis of the large data set. The study of galaxy formation is crucial to obtaining knowledge about the physics of the origin of structure in the Universe. An understanding of our Milky Way Galaxy, for which the most detailed data are available, is crucial for the development and testing of theories of galaxy formation and for the elucidation of the origins of different morphological types of galaxies. The Milky Way offers a unique opportunity for study since it is the only galaxy for which one can determine directly and in detail the true model- independent three-dimensional structure, kinematics and chemical distributions of the constituent stellar populations, by study of individual stars. Dr. Wyse's theoretical modeling of her new observational results will provide new insight into the structure and the course of the evolution of the Galaxy.

约翰·霍普金斯大学的 Rosemary Wyse 博士将利用该奖项继续研究银河系恒星的当今运动学和化学元素分布。 在先前 NSF 拨款的支持下，我们获得了 2000 多个恒星光谱。 观察将继续，但重点将转向大数据集的分析。 星系形成的研究对于获得有关宇宙结构起源的物理学知识至关重要。 了解我们的银河系（可以获得最详细的数据）对于星系形成理论的发展和测试以及阐明不同形态类型的星系的起源至关重要。 银河系提供了一个独特的研究机会，因为它是唯一一个可以通过对单个恒星的研究来直接、详细地确定组成恒星群的真实模型独立三维结构、运动学和化学分布的星系。 怀斯博士对其新观测结果的理论模型将为银河系的结构和演化过程提供新的见解。
