Top panel: [Ba/Eu] as a tracer of the s/r-ratio. While we measure systematically higher Eu abundances in the bulge star of Johnson (2013b, yellow diamond), the transition from r- to s-process dominated material is clearly seen. The dashed lines are the solar components from Burris et al. (2000) The bottom panel shows the [Ba/Y] as a proxy for the [ls/hs] ratio. The symbols are the same as in the previous figures.
