Overlapping abundance gradients and azimuthal gradients related to the spiral structure of the Galaxy

J. R. D. Lepine, P. Cruz, S. Scarano +6

The connection between some features of the metallicity gradient in the Galactic disk, best revealed by Open Clusters and Cepheids, and the spiral structure, is explored. The step-…

HD 11397 and HD 14282 - Two new barium stars?

L. Pompeia, D. M. Allen

We have performed a detailed abundance analysis of the content of s-process elements of two dwarf stars with suspected overabundace of those elements. Such stars belong to a specia…

Copper and Zinc in Bulge-Like Stars

L. Pompeia

The star formation history of a given population remains imprinted in the chemical distributions of the their individuals. The parallel study of stellar abundances and nucleosynthe…

Detailed Analysis of Nearby Bulgelike Dwarf Stars III. Alpha and Heavy-element abundances

Luciana Pompeia, Beatriz Barbuy, Michel Grenon

The present sample of nearby bulgelike dwarf stars has kinematics and metallicities characteristic of a probable inner disk or bulge origin. Ages derived by using isochrones give 1…

Detailed Analysis of Nearby Bulgelike Dwarf Stars II. Lithium Abundances

Luciana Pompeia, Beatriz Barbuy, Michel Grenon +1

Li abundances are derived for a sample of bulgelike stars with isochronal ages of 10-11 Gyr. These stars have orbits with pericentric distances, Rp, as small as 2-3 kpc and Zmax <…
