Clues from the Cosmic Past: Unraveling the Chemical History of NGC 2298

This study analyzes 13 stars in the globular cluster NGC 2298 using the Gemini South telescope. It identifies two stellar generations with distinct light element patterns and finds notable variations in heavier elements like Sc, Sr, and Eu. These differences suggest complex, uneven early chemical enrichment from supernovae and rare r-process events, highlighting the cluster’s dynamic formation history.
