Lithium Isotope Ratios in Metal-Poor Halo Stars
Abstract
Equipped with very high quality observations obtained from VLT/UVES and the new generation of 3D hydrodynamical model atmospheres, we have initiated a survey of 6Li/7Li ratios in metal-poor halo stars. Here we present the first preliminary results of this investigation, reporting four new likely detections at a similar level (6Li/7Li = 2 - 5%) to that previously found for HD 84937, BD +26°3578 and G271-162.
