碳增强贫金属（CEMP）恒星几乎占[Fe/H] 30 kpc恒星的三分之一。未来更高分辨率的光谱后续这些候选人将提供验证他们的分类，并使调查的频率CEMP-s和CEMP-no恒星在整个银河系，以进一步限制其祖先的性质。
Carbon-enhanced metal-poor (CEMP) stars comprise almost a third of stars with [Fe/H] 30 kpc. Future higher resolution spectroscopic follow-up of these candidates will provide validations of their classification and enable investigations of the frequency of CEMP-s and CEMP-no stars throughout the Galaxy, to further constrain the nature of their progenitors.
