Blue stragglers, HB and turnoff stars in 4 GC

We present a spectroscopic analysis of HST STIS and FOS low- and intermediate-resolution spectroscopy of 55 stars in four globular clusters (47 Tucanae, M3, NGC 6752, and NGC...

本研究针对4个球状星团（47 Tucanae、M3、NGC 6752及NGC……）内的55颗恒星，呈现其哈勃空间望远镜（Hubble Space Telescope, HST）搭载的太空望远镜成像摄谱仪（Space Telescope Imaging Spectrograph, STIS）与暗天体摄谱仪（Faint Object Spectrograph, FOS）获取的低、中分辨率光谱的光谱学分析成果。
