Houk 9422318 This project involves systematic two-dimensional spectral classification of nearly a quarter- million stars from Harvard's Henry Draper Catalogue, using high-quality spectroscopia plates taken with the Michigan Curtis Schmidt telescope at Cerro Tololo Inter-American Observatory in Chile and the Burrell Schmidt at Kitt Peak National Observatory near Tucson AZ. Working northward from the south celestial pole, so far over 155,000 stars have been classified and their spectral types published. From these, good temperatures, absolute brightnesses and distances can be obtained for the stars. Chemical peculiarities and binarity are also detected from many of them. This 5-year grant will support the classification of stars for Volume 6 of the Michigan Spectral Catalogue, covering declinations from +5 to +30 degrees, and the start of classification of Volume 7 stars, +35 to +90 degrees, the last installment of the project. ***

Houk 9422318 该项目涉及对来自哈佛亨利德雷珀星表的近25万颗恒星进行系统的二维光谱分类，使用的是智利托洛洛山美洲天文台的密歇根柯蒂斯施密特望远镜和亚利桑那州图森附近基特峰国家天文台的伯勒尔施密特望远镜拍摄的高质量光谱底片。 从南天极向北，到目前为止，已经有超过155，000颗恒星被分类，并公布了它们的光谱类型。 从这些数据中，可以获得恒星的良好温度、绝对亮度和距离。 化学特性和二元性也从其中许多检测。 这项为期5年的资助将支持密歇根光谱目录第6卷的恒星分类，涵盖+5至+30度的赤纬，以及第7卷恒星分类的开始，+35至+90度，这是该项目的最后一部分。 ***
