Extremely metal-poor stars in the Fornax and Carina dwarf spheroidal galaxies
R. Lucchesi, P. Jablonka, Á. Skúladóttir +6
We present our analysis of VLT/UVES and X-shooter observations of six very metal-poor stars, including four stars at [Fe/H] in the Fornax and Carina dwarf spheroidal (…
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…
Extremely metal-poor stars in SDSS fields
Piercarlo Bonifacio, Elisabetta Caffau, Patrick François +12
Some insight on the first generation of stars can be obtained from the chemical composition of their direct descendants, extremely metal-poor stars (EMP), with metallicity less tha…
First stars XIII. Two extremely metal-poor RR Lyrae stars?
C. J. Hansen, B. Nordstroem, P. Bonifacio +11
The chemical composition of extremely metal-poor stars (EMP stars; [Fe/H]<~ -3) is a unique tracer of early nucleosynthesis in the Galaxy. As such stars are rare, we wish to find c…
Non-LTE abundances of Mg and K in extremely metal-poor stars and the evolution of [O/Mg], [Na/Mg], [Al/Mg] and [K/Mg] in the Milky Way
S. M. Andrievsky, Monique Spite, S. A. Korotin +5
LTE abundances of light elements in extremely metal-poor (EMP) stars have been previously derived from high quality spectra. New derivations, free from the NLTE effects, will bette…
VLT-FLAMES Analysis of 8 giants in the Bulge Metal-poor Globular Cluster NGC 6522: Oldest Cluster in the Galaxy?
B. Barbuy, M. Zoccali, S. Ortolani +5
NGC 6522 has been the first metal-poor globular cluster identified in the bulge by W. Baade. Despite its importance, very few high resolution abundance analyses of stars in this cl…
