Carbon Enhancement in Second-Generation Stars from Faint First Supernovae with Fallback

Many of the most iron-poor stars known are strikingly rich in carbon. This study computes the relevant quantities from stated assumptions and compares them with published values. The headline results are: Fe yield Msun = 0.004; C yield Msun = 0.20; dilution Msun = 30000; [Fe/H] = -4.01; [C/Fe] = 1.46; CEMP threshold [C/Fe] = 0.7. The computed star has iron near one ten-thousandth of the solar value while its carbon-to-iron ratio sits well above the enhancement threshold. The study is simulated and computed, not measured, and its negative findings, where the computation does not support an effect, are reported at the same prominence as its positive ones.
