Lithium Isotopic Abundances in Metal-poor Halo Stars

Asplund, Martin; Lambert, David L; Nissen, Poul E; Primas, Francesca; Smith, Verne V

Description

Very high quality spectra of 24 metal-poor halo dwarfs and subgiants have been acquired with ESO's VLT/UVES for the purpose of determining Li isotopic abundances. The derived one-dimensional, non-LTE7Li abundances from the Li I 670.8 nm line reveal a pronounced dependence on metallicity but with negligible scatter around this trend. Very good agreement is found between the abundances from the Li I 670.8 nm line and the Li I 610.4 nm line. The estimated primordial7Li abundance is7Li/H =...[Show more]
