The solar photospheric abundance of phosphorus: results from CO^5BOLD 3D model atmospheres
Résumé
Aims:We determine the solar abundance of phosphorus using CO^5BOLD 3D hydrodynamic model atmospheres.
Methods: High-resolution, high signal-to-noise solar spectra of the P i lines of Multiplet 1 at 1051-1068 nm are compared to line-formation computations performed on a CO^5BOLD solar model atmosphere.
Results: We find A(P) = 5.46 ± 0.04, in good agreement with previous analyses based on 1D model atmospheres, due to the P i lines of Mult. 1 not being affected much by 3D effects. We cannot confirm an earlier claim by other authors of a downward revision of the solar P abundance by 0.1 dex when employing a 3D model atmosphere. Concerning other stars, we find modest (
