Be, V and Cu in the halo star CS 31082-001 from near-UV spectroscopy
H. Ernandes, B. Barbuy, A. Friaça +5
The 'First Stars' programme revealed the metal-poor halo star CS 31082-001 to be r-process and actinide rich, including the first measurement of a uranium abundance for an old star…

12C/13C ratio and CNO abundances in the classical very old metal-poor dwarf HD 140283
M. Spite, F. Spite, B. Barbuy
The isotope abundances provide powerful diagnostics of the chemical enrichment in our Galaxy. The star HD 140283 is one of the best-studied very metal-poor dwarf stars. It is very…

Origin of the heavy elements in HD 140283. Measurement of europium abundance
C. Siqueira Mello, B. Barbuy, M. Spite +1
HD 140283 is a nearby (V=7.7) subgiant metal-poor star, extensively analysed in the literature. Although many spectra have been obtained for this star, none showed a signal-to-nois…
