The photospheric solar oxygen project: I. Abundance analysis of atomic lines and influence of atmospheric models
Elisabetta Caffau, Hans-G. Ludwig, Matthias Steffen +5
The solar oxygen abundance has undergone a major downward revision in the last decade, the most noticeable one being the update including 3D hydrodynamical simulations to model the…
The solar photospheric abundance of hafnium and thorium. Results from CO5BOLD 3D hydrodynamic model atmospheres
Elisabetta Caffau, L. Sbordone, H. -G. Ludwig +3
Context: The stable element hafnium (Hf) and the radioactive element thorium (Th) were recently suggested as a suitable pair for radioactive dating of stars. The applicability of t…
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…
3-D hydrodynamic simulations of convection in A stars
O. Kochukhov, B. Freytag, N. Piskunov +1
Broadening and asymmetry of spectral lines in slowly rotating late A-type stars provide evidence for high-amplitude convective motions. The properties of turbulence observed in the…
