On The Oxygen Abundance of HE 0107-5240

Bessell, Michael; Christlieb, Norbert; Gustafsson, Bengt


We have determined the oxygen abundance of HE 0107-5240 from UV-OH lines detected in VLT/UVES spectra. Using a plane-parallel LTE model atmosphere, we derive [O/Fe] = +2.3, and a similar analysis of CD -38°245 yields [O/Fe] = +0.9. We estimate systematic
