Distribution of [Ba/Fe] vs. [Eu/Fe]. The red distribution represents our default model A. The grey distribution is computed with an initial enhancement of [r/ Fe] ini = 1. The dotted lines indicate the thresholds [Ba/Fe] = + 0.5 and [Eu/Fe] = 1 that define CEMP-s and CEMP-s/r stars, respectively. The crosses indicate the observed CEMP-s stars with [Eu/Fe] < + 1. CEMP-s/r are shown as blue circles. The + symbol in the top-left corner shows the average observed uncertainty.
