[Ba/Fe] abundance as a function of cluster age for dwarf stars in Lupus (this work) and other regions (from the literature). The red diamond represents the mean value of the most reliable Ba abundances obtained for the two warmest targets (see text and Table 1). Cluster abundances and ages were taken from D’Orazi et al. (2009, 2012), De Silva et al. (2013), and Reddy & Lambert (2015). The dashed line represents the Galactic chemical evolution model developed by D’Orazi et al. (2009) adopting enhanced s-process yields from AGB stars.
