Comparison of the neutron-capture elements. Left panel: [Sr/Fe] vs. [Fe/H]. Central panel: [Ba/Fe] vs [Fe/H]. Empty symbols denote upper limits on the vertical axis. Right panel: [Sr/Ba] vs. [Ba/Fe]. Grey circles are MW stars from SAGA (Suda et al. 2008). Magenta markers denote UFDs: Coma Berenice (ComBer) stars are from Frebel et al. (2010) and Waller et al. (2023); Bootes I (BooI) stars are from Feltzing et al. (2009), Norris et al. (2010), Gilmore et al. (2013), Ishigaki et al. (2014), and Frebel et al. (2016); Gru I stars are from Ji et al. (2019); Tucana II (TucII) stars are from Ji et al. (2016a) and Chiti et al. (2018); Segue 1 (Seg1) stars are from Frebel et al. (2014); Hercules (Her) stars are from Koch et al. (2008), Koch et al. (2013), and François et al. (2016); Reticulum II (RetII) are from Ji et al. (2016b) and Roederer et al. (2016). Black markers indicate classical DGs: Sculptor (Scl) are from Mashonkina et al. (2017b) and Hill et al. (2019), while Ursa Minor (UMi) stars are from Mashonkina et al. (2017b) and Sestito et al. (2023c), both DGs have been complemented with data from SAGA. All the datasets are from 1D LTE analyses. Uncertainties for stars from the literature are on the same scale as our values.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
