Analysis of Results from Volumes 1 - 4 of the Michigan Spectral Catalogue

根据光谱对恒星进行分类是 是天文学研究中一个重要的、历史悠久的部分。 的 光谱给出了恒星温度的信息， 成分、进化阶段、绝对亮度， 的距离. 我们对恒星演化的了解 银河系动力学是基于光谱中包含的信息 星表 主要研究者（PI）建议继续其工作， 目前由NSF资助，关于二维分类， 明星从哈佛的亨利德雷珀（高清）目录。 迄今为止， 恒星已被分类，其光谱类型发表在 密歇根光谱目录在目前的提案中， PI打算为目录的第5卷进行恒星分类， 位于南半球， 第六卷的恒星分类 本科和研究生 学生将参与，虽然分类的关键任务， 根据恒星的光谱， PI，以保持一致性。

The classification of stars according to their optical spectra is an important and time honored part of astronomical research. The spectra give information about the stars' temperatures, compositions, evolutionary stages, absolute brightnesses, and distances. Much of what we know about stellar evolution and Galactic dynamics is based on the information contained in spectral catalogues of stars. The Principal Investigator (PI) proposes to continue with her work, currently funded by NSF, on the two-dimensional classification of stars from Harvard's Henry Draper (HD) Catalogue. To date, 130,000 stars have been classified and their spectral types published under the title Michigan Spectral Catalogue. In the current proposal, the PI intends to classify stars for Volume 5 of the catalogue, all of which lie in the Southern Hemisphere; and to start the classification of stars for Volume 6. Undergraduate and graduate students will participate, though the crucial task of classifying the stars according to their spectra will be done exclusively by the PI in order to maintain uniformity.
