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…
