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…
The solar photospheric abundance of europium. Results from CO5BOLD 3-D hydrodynamical model atmospheres
A. Mucciarelli, E. Caffau, B. Freytag +2
Context. Europium is an almost pure r-process element, which may be useful as a reference in nucleocosmochronology. Aims. To determine the photospheric solar abundance using CO5BOL…
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…
