From the left [Sr/Ba], [Zr/Ba] and [Rb/Ba] vs. [Fe/H] in the halo; the density plot is the distribution of simulated long-living stars for our models. Superimposed, we show the abundance ratios for halo stars (data from Frebel 2010a). The symbols for the Frebel (2010a) data are black dots for normal stars, and black open circles for stars without carbon measurement.
