Integrated Spectra of Milky Way Globular Cluster
Tatiana Coelho de Moura, Marina Trevisan, Beatriz Barbuy +1
Integrated spectra of Milky Way globular clusters (GCs) are reproduced by computing synthetic spectra taking into account individual element abundances. Five clusters were selected…
Heavy elements in old very metal-rich stars
M. Trevisan, B. Barbuy
We studied a sample of high proper motion, old and metal-rich dwarf stars, selected from the NLTT catalogue. The low pericentric distances and eccentric orbits of these solar neigh…
High-resolution abundance analysis of red giants in the globular cluster NGC 6522
B. Barbuy, C. Chiappini, E. Cantelli +11
The [Sr/Ba] and [Y/Ba] scatter observed in some galactic halo stars that are very metal-poor stars and in a few individual stars of the oldest known Milky Way globular cluster NGC…
Analysis of old very metal rich stars in the solar neighbourhood
M. Trevisan, B. Barbuy, K. Eriksson +3
A sample of mostly old metal-rich dwarf and turn-off stars with high eccentricity and low maximum height above the Galactic plane has been identified. From their kinematics, it was…
