Abstract In this review we discuss possible systematic errors inherent in classical 1D LTE abundance analyses of late-type stars for the light elements (here: H, He, Li, Be and B). The advent of realistic 3D hydrodynamical model atmospheres and the availability of non-LTE line formation codes place the stellar analyses on a much firmer footing and indeed drastically modify the astrophysical interpretations in many cases, especially at low metallicities. For the Teff-sensitive hydrogen lines… Expand


Multi-level 3D non-LTE computations of lithium lines in the metal-poor halo stars HD 140283 and HD 84937
The lithium abundances in metal-poor halo stars are of importance for cosmology, galaxy evolution and stellar structure. In an attempt to study possible systematic errors in the derived LiExpand
New light on stellar abundance analyses: Departures from LTE and homogeneity.
▪ Abstract The information on the chemical compositions of stars encoded in their spectra plays a central role in contemporary astrophysics. Stellar element abundances are, however, not observed: toExpand
Convection and 6Li in the atmospheres of metal-poor halo stars
Abstract Based on 3D hydrodynamical model atmospheres computed with the CO5BOLD code and 3D non-LTE (NLTE) line formation calculations, we study the effect of the convection-induced line asymmetry onExpand
Departures from LTE for neutral Li in late-type stars
We perform non-LTE calculations of lithium in late-type stars for a wide range of stellar parameters, including quantum mechanical cross-sections for collisions with neutral hydrogen and th eExpand

Aims. A detailed study is presented, including estimates of the impact on elemental abundance analysis, of the non-local thermodynamic equilibrium (non-LTE) formation of the high-excitation neutralExpand
Lithium isotopic abundances in metal-poor halo stars
Very high quality spectra of 24 metal-poor halo dwarfs and subgiants have been acquired with ESO's VLT/UVES for the purpose of determining Li isotopic abundances. The derived one-dimensional, non-LTEExpand
Kinetic equilibrium of iron in the atmospheres of cool stars - III. The ionization equilibrium of selected reference stars
Non-LTE line formation calculations of Fei are performed for a small number of reference stars to investigate and quantify the eciency of neutral hydrogen collisions. Using the atomic model that wasExpand
6Li/7Li estimates for metal-poor stars
Context. The presence of the lithium-6 isotope in some metal-poor stars is a matter of surprise because of the high values observed. Non-standard models of Big Bang nucleosynthesis and pre-GalacticExpand
3D Hydrodynamical Simulations of Surface Convection in Red Giant Stars. Impact on spectral line formation and abundance analysis
We investigate the impact of 3D hydrodynamical model atmospheres of red giant stars at different metallicities on the formation of spectral lines of a number of ions and molecules. We carry outExpand
