Chemical Abundance Signature of J0023+0307: A Second-generation Main-sequence Star with [Fe/H]
We present a chemical abundance analysis of the faint halo metal-poor main-sequence star J0023+0307, with [Fe/H] <-6.3, based on a high-resolution (R ∼ 35,000) Magellan/MIKE spectrum. The star was originally found to have [Fe/H] <-6.6 based on a Ca ii K measurement in an R ∼ 2500 spectrum. No...
