Line shift, line asymmetry, and the 6Li/7Li isotopic ratio determination
Roger Cayrel, Matthias Steffen, Hum Chand +6
Context: Line asymmetries are generated by convective Doppler shifts in stellar atmospheres, especially in metal-poor stars, where convective motions penetrate to higher atmospheri…
The solar photospheric abundance of phosphorus: results from co5bold 3D model atmospheres
Elisabetta Caffau, Matthias Steffen, Luca Sbordone +2
aims: We determine the solar abundance of phosphorus using co5bold 3D hydrodynamic model atmospheres. method: High resolution, high signal-to-noise solar spectra of the PI lines of…
Sulphur abundances from the SI near-infrared triplet at 1045 nm
Elisabetta Caffau, Rosanna Faraggiana, Piercarlo Bonifacio +2
context : Unlike silicon and calcium, sulphur is an alpha-element which does not form dust. Some of the available observations of the evolution of sulphur with metallicity indicate…
