Two-Dimensional Classification of the HD Stars

这个项目包括对哈佛大学亨利·德雷珀目录中近25万颗恒星进行系统的二维光谱分类，使用智利塞罗·托洛洛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板。到目前为止，已经对15.5万多颗恒星进行了分类，并公布了它们的光谱类型。从这些数据中，可以获得恒星的温度、绝对亮度和距离。化学特性和二值性也从其中的许多检测。这项为期5年的拨款将支持《密歇根光谱目录》第6卷的恒星分类，涵盖+5到+30度的赤纬，并开始对第7卷的恒星进行分类，+35到+90度，这是该项目的最后一部分。* * *

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. ***
