Spectroscopic Study of Ba and CEMP-s Stars: Mass Distribution of AGB Progenitors

Spectroscopic Study of Ba and CEMP-s Stars: Mass Distribution of AGB Progenitors

We have performed detailed high-resolution spectroscopic analysis on seven metal-poor stars (BD+75 348, BD+09 3019, HD238020, HE0319–0215, HE0507–1653, HE0930–0018, HE1023–1504) and derived their atmospheric parameters T _eff , log g , [Fe/H], and microturbulent velocity ( ξ ). The metallicity range...
