Metal-poor stars from the HES using CH G-band

We describe a new method to search for metal-poor candidates from the Hamburg/ESO objective-prism survey (HES) based on identifying stars with apparently strong CH G-band...本文提出一种全新方法，可通过识别具有显著强CH G带（CH G-band）特征的恒星，从汉堡/欧洲南方天文台物端棱镜巡天（Hamburg/ESO Objective-Prism Survey，缩写HES）中搜寻贫金属候选体。
