Sc and neutron-capture abundances in Galactic low- and high-alpha field halo stars
C. K. Fishlock, D. Yong, A. I. Karakas +5
We determine relative abundance ratios for the neutron-capture elements Zr, La, Ce, Nd, and Eu for a sample of 27 Galactic dwarf stars with -1.5 < [Fe/H] <-0.8. We also measure the…
High-precision abundances of Sc, Mn, Cu, and Ba in solar twins. Trends of element ratios with stellar age
P. E. Nissen
A previous study of correlations between element abundance ratios, [X/Fe], and ages of solar twin stars is extended to include Sc, Mn, Cu, and Ba. HARPS spectra with S/N > 600 are…
Stroemgren survey for Asteroseismology and Galactic Archaeology: let the SAGA begin
L. Casagrande, V. Silva Aguirre, D. Stello +17
Asteroseismology has the capability of precisely determining stellar properties which would otherwise be inaccessible, such as radii, masses and thus ages of stars. When coupling t…
Abundances of neutron-capture elements in G 24-25. A halo-population CH subgiant
S. Liu, P. E. Nissen, W. J. Schuster +3
The differences between the neutron-capture element abundances of halo stars are important to our understanding of the nucleosynthesis of elements heavier than the iron group. We p…
