Damped Lyman alpha systems at z=0.68 and z=1.15 towards HE 1122-1649 and HE 0515-4414
A. de la Varga, D. Reimers, D. Tytler +2
Detailed analysis of the spectral lines from two low redshift damped Lyman alpha absorbers (DLA) confirms that they are a heterogeneous population. Both systems have low metal abun…

Oxygen Abundance Determination in Very Metal-Deficient Giants: Permitted O I Lines Versus Forbidden [O I] Lines
Y. Takeda, M. Takada-Hidai, S. Sato +4
The abundance of oxygen was determined for selected very metal-poor G-K stars (six giants and one turn-off star) based on the high S/N and high-resolution spectra observed with Kec…
