Abundances of Y, Ba, La, and Eu vs. metallicities. The abundances derived in this work (circles) are compared with the thin- (green squares) and thick-disk (red stars) stars and the intermediate population (blue diamonds) from Edvardsson et al. (1993), Reddy et al. (2003, 2006), Bensby et al. (2005), Nissen & Schuster (2011), Mishenina et al. (2013), and Ishigaki et al. (2013). Grey crosses represent stars with no available U, V, and W velocities, therefore no membership assignment was possible. The symbols representing our sample stars are filled according to their membership classification: thin disk (green), thick disk (red) and intermediate population (blue).
