First stars XVI. STIS/HST abundances of heavy-elements in the uranium-rich star CS 31082-001
C. Siqueira Mello, M. Spite, B. Barbuy +14
Detailed abundances of the elements produced by r-process nucleosynthesis in various circumstances are our best observational clues to their origin, since the site(s) of r-element…
6Li detection in metal-poor stars: can 3D model atmospheres solve the second lithium problem?
M. Steffen, R. Cayrel, E. Caffau +3
The presence of 6Li in the atmospheres of metal-poor halo stars is usually inferred from the detection of a subtle extra depression in the red wing of the 7Li doublet line at 670.8…
NLTE determination of the calcium abundance and 3D corrections in extremely metal-poor stars
Monique Spite, S. M. Andrievsky, F. Spite +6
(Abridged) Extremely metal-poor stars contain the fossil records of the chemical composition of the early Galaxy. The NLTE profiles of the calcium lines were computed in a sample o…
An extremely primitive halo star
E. Caffau, P. Bonifacio, P. François +11
The early Universe had a chemical composition consisting of hydrogen, helium and traces of lithium1, almost all other elements were created in stars and supernovae. The mass fracti…
A primordial star in the heart of the Lion
E. Caffau, P. Bonifacio, P. François +14
Context: The discovery and chemical analysis of extremely metal-poor stars permit a better understanding of the star formation of the first generation of stars and of the Universe…
