Left : [C/Fe] as a function of metallicity. The dashed orange line is [C/Fe] = +0.7, while the black dashed line is the other threshold commonly assumed in the literature for CEMP stars, [C/Fe] = +1. Right : The absolute C abundance as a function of [Fe/H]. The dashed blue line represents the solar value A(C)⊙ = 8.43 (Asplund et al. 2009).
