Carbon abundances ([C/Fe]) as a function of [Fe/H] for the five CEMP stars compared to literature samples. Specifically, we compare to results from A. Chiti et al. (2024), who report abundances for some of the most metal-poor stars known in the LMC, along with results from APOGEE spectra in SDSS-IV DR17. The commonly used definition for CEMP ([C/Fe] > 0.7) is shown as a black dashed line, with the five stars from this work being the only stars above said line.
