Mass distribution for giant barium stars (thus excluding barium dwarfs, CH stars, and CH subgiants), from a comparison with the STAREVOL evolutionary tracks, for the three metallicities [Fe/H] = 0, [Fe/H] =−0.25, and [Fe/H] =−0.5. Adopting Teff ± σTeff and L ± σL, we determine the red () and green (+) histograms. The vertical dashed line indicates the peak of the [Fe/H] =−0.25 distribution.
