Unveiling the Chemical Legacy of the Sagittarius Dwarf Galaxy

The study examines the Sagittarius dwarf galaxy (Sgr dSph), revealing its star formation history and chemical evolution through high-resolution spectroscopy of 111 giant stars. The findings highlight a slower star formation rate compared to the Milky Way, distinct elemental patterns from neutron-capture processes, and contributions from ancient and younger stellar populations. Sgr's evolution offers insights into galactic mergers and enrichment in the Milky Way's halo.
