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…
Lithium-rich giants in the Sagittarius dSph Tidal Streams
L. Monaco, P. Bonifacio
The nature and origin of Lithium rich giant stars is still matter of debate. In the contest of our spectroscopic survey of giants in the tidal streams of the Sagittarius dwarf sphe…
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…
