Average [α/Fe] vs. [Fe/H] (left), [Sr/Ba] vs. [Ba/Fe] (middle), and [Ba/Eu] vs. [Ba/H] (right) abundances for our Sgr stars. Legends are the same as Figure 3. The left panel showcases the one star, Sgr438 with low [α/Fe] abundances, whose origin we discuss in detail in Section 4.1. The middle panel shows one potential UFD star, Sgr471, discussed in Section 4.4 with the rest of the sample distributed above the empirical cut. The right panel shows the confirmed r-process stars (Section 4.5) covering a range of −0.7 < [Ba/Eu] < −0.3, consistent with being enriched primarily by r-process enrichment events.
