First stars VI - Abundances of C, N, O, Li, and mixing in extremely metal-poor giants. Galactic evolution of the light elements
M. Spite, R. Cayrel, B. Plez +11
We have investigated the poorly-understood origin of nitrogen in the early Galaxy by determining N abundances in 35 extremely metal-poor halo giants (22 stars have [Fe/H]<-3.0) usi…
Heavy elements and chemical enrichment in globular clusters
G. James, P. Francois, P. Bonifacio +3
High resolution (R > 40 000) and high S/N spectra have been acquired with UVES on the VLT-Kueyen (Paranal Observatory, ESO Chile) for several main sequence turnoff stars (V ~ 17 ma…
ATLAS and SYNTHE under Linux
L. Sbordone, P. Bonifacio, F. Castelli +1
We have successfully ported under GNU Linux ATLAS 9, the widely used stellar atmosphere modeling code, as well as both the SYNTHE suite of programs, its ``companion'' for spectral…
Search for alpha variation in UVES spectra: Analysis of C IV and Si IV doublets towards QSO 1101-264
A. F. Martinez Fiorenzano, G. Vladilo, P. Bonifacio
Motivated by previous studies of QSO spectra that reported a variation of the fine structure constant alpha, a search for C IV and Si IV doublets was conducted in the absorption sp…
Sgr dSph: a bridge between Dwarf Galaxies and DLAs?
L. Sbordone, P. Bonifacio, G. Marconi +2
We present abundances for 12 giants in the Sagittarius Dwarf Spheroidal Galaxy (Sgr dSph) obtained from VLT - UVES spectra. Moving on a short period, polar orbit around the Milky W…
Chemical abundances in Terzan 7 from UVES spectra
L. Sbordone, P. Bonifacio, G. Marconi +1
We present chemical abundances for Mg, Si, Ca and Fe for three red giants in the sparse globular cluster Terzan 7, physically associated to the Sagittarius Dwarf Spheroidal Galaxy…
