Abundances of iron-peak elements in accreted and in situ born Galactic halo stars
P. E. Nissen, A. M. Amarsi, Á. Skúladóttir +1
Previous work on the abundances of C, O, Na, Mg, Si, Ca, Ti, Cr, Mn, Fe, Ni, Cu, and Zn in low-alpha (accreted) and high-alpha (in situ born) halo stars is extended to include the…
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…
Two-site CCD observations and spectroscopy of HD 207331: a new Scuti variable in Cygnus
L. Fox Machado, W. J. Schuster, C. Zurita +2
The results of an observational campaign on the new Scuti pulsator \astrobj{HD~207331} are reported. The star was observed photometrically from August 26 to September 2, 2009 f…
uvby(-) photometry of high-velocity and metal-poor stars X. Stars of very low metal abundance: observations, reddenings, metallicities, classifications, distances, and relative ages
W. J. Schuster, T. C. Beers, R. Michel +2
uvby(--) photometry has been obtained for an additional 411 very metal-poor stars selected from the HK survey, and used to derive basic parameters such as interstellar reddening…
