Cumulative distribution of eccentricities for CH/CEMP-s stars (blue curve in lower panel) and barium stars (black curve in lower panel). The solid black line corresponds to the full barium star sample, whereas the dashed red line corresponds to the barium star sample restricted to e< 0.5. In the upper panel, the red line corresponds to metal-deficient non-CEMP giants and the solid black curve to K giants in open clusters.
