Oxygen line formation in 3D hydrodynamical model atmospheres
M. Asplund
The formation of [O I], O I and OH lines in metal-poor stars has been studied by means of 3D hydrodynamical model atmospheres. For O I detailed 3D non-LTE calculations have been pe…
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…
Line formation in solar granulation: II. The photospheric Fe abundance
M. Asplund, AA. Nordlund, R. Trampedach +1
The solar photospheric Fe abundance has been determined using realistic ab initio 3D, time-dependent, hydrodynamical model atmospheres. The study is based on the excellent agreemen…
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.…
