Spectroscopy of low-metallicity star candidates

We present results from an observing campaign to identify low-metallicity stars in the Best & Brightest Survey. From medium-resolution (R~1200-2000) spectroscopy of 857...我们报道了「最佳与最亮巡天（Best & Brightest Survey）」项目中用于识别低金属丰度恒星的观测计划所取得的研究成果。基于对857颗恒星的中分辨率（光谱分辨率R≈1200-2000）光谱观测……
