Projection map obtained using t-SNE. The gray stars are the sample from GALAH used in da Silva & Smiljanic (2023). The four groups defined in that work (Gaia Enceladus, prograde, retrograde, and most retrograde) are colored in green, blue, light brown, and dark purple, respectively. The cyan stars are 28 RPE stars with [Eu/Fe] ≥ + 1.7 dex found in the SAGA database (Soubiran et al. 2024) complemented by five stars from Roederer et al. (2024). The Sun is added as reference.
