The oxygen abundance of the ultra-metal-poor star HE 0557-4840

Norris, John; Christlieb, N; Bessell, Michael; Asplund, Martin; Eriksson, K.; Korn, A. J.

Description

We present a high-resolution ultraviolet (UV) spectrum of the ultra-metal-poor (UMP) carbon-enhanced red giant HE 0557-4840 (Teff/log g/[Fe/H] = 4900/2.2/-4.8). Combining these data with earlier observations, the radial velocity is 212.0 ± 0.4kms-1, with
