Solar Chemical Abundances Determined with a CO5BOLD 3D Model Atmosphere
Elisabetta Caffau, Hans-Günter Ludwig, Matthias Steffen +2
In the last decade, the photospheric solar metallicity as determined from spectroscopy experienced a remarkable downward revision. Part of this effect can be attributed to an impro…
The metal-poor end of the Spite plateau. 1: Stellar parameters, metallicities and lithium abundances
L. Sbordone, P. Bonifacio, E. Caffau +16
We present VLT-UVES Li abundances for 28 halo dwarf stars between [Fe/H]=-2.5 and -3.5, 10 of which have [Fe/H]<-3. Four different T_eff scales have been used. Direct Infrared Flux…
The solar photospheric abundance of carbon.Analysis of atomic carbon lines with the CO5BOLD solar model
E. Caffau, H. -G. Ludwig, P. Bonifacio +5
The use of hydrodynamical simulations, the selection of atomic data, and the computation of deviations from local thermodynamical equilibrium for the analysis of the solar spectra…
Convection and 6Li in the atmospheres of metal-poor halo stars
M. Steffen, R. Cayrel, P. Bonifacio +2
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 as…
