The low-mass metal-poor stars in the Galaxy that preserve their atmosphere, chemical imprints of gas clouds from which they were formed can be used as probes to get insight into origin and evolution elements early galaxy, star formation nucleosynthesis. Among stars, a large fraction, so-called carbon-enhanced (CEMP) exhibits high abundance carbon. These exhibit diverse patterns, particularly for heavy elements, based on are classified different groups. diversity patterns points at scenarios. Hence, accurate classification CEMP knowledge distribution is essential understand role contribution each group. While CEMP-s CEMP-r/s binary interactions very low metallicity, CEMP-no probe properties first To exploit full potential Galactic archaeology homogeneous analysis class extremely important. Our efforts towards, contributions providing an improved scheme characterizing companion asymptotic giant branch (AGB) CH, CEMP-no, systems discussed. Some recent results obtained low- high-resolution spectroscopic number CH candidates highlighted.
