Possible signature of hypernova nucleosynthesis in a beryllium rich halo dwarf
R. Smiljanic, L. Pasquini, F. Primas +3
As part of a large survey of halo and thick disc stars, we found one halo star, HD 106038, exceptionally overabundant in beryllium. In spite of its low metallicity, [Fe/H] = -1.26,…
Abundance analysis of barium and mild barium stars
R. Smiljanic, G. F. Porto de Mello, L. da Silva
High signal to noise, high resolution spectra were obtained for a sample of normal, mild barium, and barium giants. Atmospheric parameters were determined from the FeI and FeII lin…
Evidence for rotation-induced mixing in evolved intermediate mass stars
R. Smiljanic, B. Barbuy, J. R. De Medeiros +1
Many observational results seem to indicate more efficient mixing processes in intermediate mass stars (5-20 M) than the expected by the standard models. These processes…
CNO in evolved intermediate mass stars
R. Smiljanic, B. Barbuy, J. R. De Medeiros +1
In order to investigate the possible influence of rotation on the efficiency of the first dredge-up we determined atmospheric parameters, masses, and abundances of carbon, nitrogen…
