The beryllium abundance in the very metal-poor halo star G 64-12 from VLT/UVES observations
F. Primas, M. Asplund, P. E. Nissen +1
We report on a new spectroscopic analysis of the very metal deficient star G 64-12 ([Fe/H]=-3.3), aimed at determining, for the first time, its Be content. The spectra were observe…

The lithium isotope ratio in the metal-poor halo star G271-162 from VLT/UVES observations
P. E. Nissen, M. Asplund, V. Hill +1
A high resolution (R = 110.000), very high S/N (>600) spectrum of the metal-poor turnoff star G271-162 has been obtained in connection with the commissioning of UVES at VLT/Kueyen.…
