Galactic Chemistry, Structure and Kinematics: Towards an Understanding of the Galaxy

约翰霍普金斯大学的罗斯玛丽·怀斯博士将利用这一奖项继续她对银河系恒星的现代运动学和化学元素分布的研究。在之前美国国家科学基金会的资助下，已经获得了2000多个恒星光谱。观察将继续，但重点将转移到对大数据集的分析上。星系形成的研究对于获得关于宇宙结构起源的物理学知识是至关重要的。对我们银河系的了解对于发展和检验星系形成理论和阐明不同形态类型星系的起源至关重要，因为银河系拥有最详细的数据。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直接和详细地确定组成恒星群体的真实独立于模型的三维结构、运动学和化学分布的星系。怀斯博士对她的新观测结果的理论建模将为银河系的结构和演化过程提供新的见解。

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.
