Barium Stars Across the Milky Way: Probing Their Origins via the GALAH Survey

Jaden Levine, Catherine Manea, Keith Hawkins +4

Barium stars are unusually enriched in barium ([Ba/Fe] >= 1.0 dex) and not predicted by current Galactic chemical evolution models. Previous observations of barium stars have found…

Exploring the History of Stellar Mergers with Chemistry: Examining the Origins of Massive $I^\pm$ -Enriched Stars using Carbon Isotope Ratios

Zachary G. Maas, Keith Hawkins, Jeffrey M. Gerber +2

Recently discovered massive $I^\pm$ -enriched (MAE) stars have surface chemistry consistent with members of the older thick disk Milky Way population but high masses ( $\sim$ 1.5 - 3 M$…
