Abundances of neutron-capture elements as a function of RG. The radial gradients we derived for Cepheid stars (dashed line) are compared with field dwarfs analyzed by Reddy et al. (2003, R03, magenta squares) and with field dwarfs (crosses) and giants (open circles) analyzed by Simmerer et al. (2004, S04). From the latter only stars with [Fe/H] > −1.0 are plotted. RSGs in the Scutum cluster analyzed by Origlia et al. (2013, O13, triangles) are also shown.
