A Catalog of 486 Barium Stars Identified in GALAH DR4

The Astrophysical Journal Supplement Series
We present a catalog of 486 Ba stars identified in the GALAH DR4 survey using high-resolution spectra and precise abundance measurements. The sample was selected based on s- process enrichment criteria involving the abundances of Ba and La relative to Eu,

Asymptotic Giant Branch Mass-loss Rates and Metal Yields from Scaled Mixing-length and Mass-loss Parameters

The Astrophysical Journal
Stars on the asymptotic giant branch (AGB) enrich the interstellar medium with carbon, nitrogen, and dust, which in turn boost cooling and promote future generations of planet and star formation.
