Neutron-capture element deficiency of the Hercules dwarf spheroidal galaxy
Andreas Koch, Sofia Feltzing, Daniel Aden +1
We present an assessment of the barium abundance ratios for red giant member stars in the faint Hercules dwarf spheroidal (dSph) galaxy. Our results are drawn from intermediate-res…
An intermediate-band photometric study of the "Globular Cluster" NGC 2419
Andreas Koch, Matthias Frank, Sofia Feltzing +3
NGC 2419 is one of the remotest star clusters in the Milky Way halo and its exact nature is yet unclear: While it has traits reminiscent of a globular cluster (GC), its large radiu…
Signatures of an intermediate-age metal-rich bulge population
T. Bensby, S. Feltzing, A. Gould +8
We have determined detailed elemental abundances and stellar ages for a sample of now 38 microlensed dwarf and subgiant stars in the Galactic bulge. Stars with sub-solar metallicit…
The chemical evolution of the Galactic Bulge seen through micro-lensing events
Sofia Feltzing, Thomas Bensby, Jorge Meléndez +6
Galactic bulges are central to understanding galaxy formation and evolution. Here we report on recent studies using micro-lensing events to obtain spectra of high resolution and mo…
Chemical evolution of the Galactic bulge as traced by microlensed dwarf and subgiant stars. IV. Two bulge populations
T. Bensby, D. Adén, J. Meléndez +21
[ABRIDGED] Based on high-resolution (R~42000 to 48000) and high signal-to-noise (S/N~50 to 150) spectra obtained with UVES/VLT, we present detailed elemental abundances (O, Na, Mg,…
An abundance study of red-giant-branch stars in the Hercules dwarf spheroidal galaxy
D. Adén, K. Eriksson, S. Feltzing +3
Using high-resolution spectroscopy, we provide a determination of [Fe/H] and [Ca/H] for confirmed red-giant branch member stars of the Hercules dwarf spheroidal galaxy. Based on th…
