The fraction of the odd Ba isotopes, fodd,Ba, versus [Ba/H] (top panel), [Ba/Eu] (middle panel), and [Eu/Fe] (bottom panel). Filled circle and Asterisk represent HE 0338-3945 and CS 31082-001, respectively. Uncertainties are shown by short horizontal and vertical lines. Dotted horizontal lines indicate the fodd,Ba values, 0.18 for the solar system, 0.46 for the pure r-process, and 0.11 for the pure s-process in production of the solar barium abundance predicted by Arlandini et al. (1999).
