Chemical abundance spaces commonly used to distinguish between accreted and in situ stars. The top panel shows [Mg/Mn] as a function of the [Al/Fe] abundances, with the APOGEE DR17 control sample in the background (see the text for details). The dashed line shows the region typically populated by accreted stars. The middle panel shows [Mg/Mn] as a function of the [Na/Fe] abundances. The bottom panel shows [Eu/Mg] as a function of [Fe/H]. The bottom two panels show GALAH DR3 data in the background since GALAH provides [Na/Fe] and [Eu/Fe] measurements.
