Presidential Young Investigator (PYI) Award - The Mass Distribution of The Inner Galaxy

特恩德鲁普博士将利用这一总统青年研究者奖 来支持他对地球内部隆起、光环和圆盘的研究， 银河 恒星丰度和运动学将被测量， 确定银河系内部的质量分布， 限制了我们银河系形成的模型。 我们的星系核膨胀的结构和恒星数量 在过去的十年里，银河系一直是人们非常感兴趣的主题。 然而，许多基本问题尚未得到解答： 膨胀和银河系的圆盘相互作用？ 做凸起和光晕 有一个单独的历史，或者可以理解为不同的 是同一个古老恒星群的表现吗 是什么 隆起、盘和晕的形成顺序，以及 大规模的进程，导致目前的结构， 银河系？ 热与热的相对重要性是什么？ 旋转支撑在凸起，并有酒吧或 其他大宗议案？ 特恩德鲁普博士的研究将解决这些问题 问题与广泛的观察调查的运动学 以及银河系核球中恒星的丰度。

Dr. Terndrup will use this Presidential Young Investigator Award to support his research on the inner bulge, halo, and disk of our Galaxy. Stellar abundances and kinematics will be measured to determine the mass distribution of the inner Galaxy and to constrain models of the formation of our Galaxy. The structure and stellar population of the nuclear bulge of our Galaxy have been subjects of great interest in the last ten years. Many basic questions, however, are yet unanswered: How do the bulge and the disk of the Galaxy interact? Do the bulge and halo have a separate history, or can they be understood as different manifestations of the same old stellar population? What was the order of formation of the bulge, disk, and halo, and what were the large-scale processes that led to the current structure of the Milky Way? What is the relative importance of thermal versus rotational support in the bulge, and are there signs of bars or other bulk motions? Dr. Terndrup's research will address these questions with an extensive observational survey of the kinematics and abundances of stars in the Galactic bulge.
