The Evolution of the C/O Ratio in Metal-poor Halo Stars

Akerman, Chris J; Carigi, Leticia; Nissen, Poul E; Pettini, Max; Asplund, Martin


We report new measurements of carbon and oxygen abundances in 34 F and G dwarf and subgiant stars belonging to the halo population and spanning a range of metallicity from [Fe/H] = -0.7 to -3.2. The survey is based on observations of four permitted lines
