Many Roads Lead to Lithium: Formation Pathways For Lithium-rich Red Giants

Many Roads Lead to Lithium: Formation Pathways For Lithium-rich Red Giants

Stellar models predict that lithium (Li) inside a star is destroyed during the first dredge-up phase, yet 1.2% of red giant stars are Li-rich. We aim to uncover possible origins of this population, by analyzing 1099 Li-rich giants ( A (Li) ≥ 1.5) in GALAH DR3. To expose peculiar traits of Li-rich st...
