Chemical evolution of the Galactic bulge as traced by microlensed dwarf and subgiant stars. II. Ages, metallicities, detailed elemental abundances, and connections to the Galactic thick disc
T. Bensby, S. Feltzing, J. A. Johnson +13
The Bulge is the least understood major stellar population of the Milky Way. Most of what we know about the formation and evolution of the Bulge comes from bright giant stars. The…
A new low mass for the Hercules dSph: the end of a common mass scale for the dwarfs?
D. Adén, M. I. Wilkinson, J. I. Read +5
We present a new mass estimate for the Hercules dwarf spheroidal galaxy (dSph), based on the revised velocity dispersion obtained by Aden et al. (2009, arXiv:0908.3489). The remova…
Complexity in small-scale dwarf spheroidal galaxies
Andreas Koch, Daniel Adén, Eva K. Grebel +1
Our knowledge about the chemical evolution of the more luminous dwarf spheroidal (dSph) galaxies is constantly growing. However, little is known about the enrichment of the ultrafa…
A photometric and spectroscopic study of the new dwarf spheroidal galaxy in Hercules
D. Adén, S. Feltzing, A. Koch +8
Our aim is to provide as clean and as complete a sample as possible of red giant branch stars that are members of the Hercules dSph galaxy. With this sample we explore the velocity…
Elemental abundances in the Galactic bulge from microlensed dwarf stars
T. Bensby, S. Feltzing, J. A. Johnson +11
We present elemental abundances of 13 microlensed dwarf and subgiant stars in the Galactic bulge, which constitute the largest sample to date. We show that these stars span the ful…
OGLE-2009-BLG-076S - The most metal-poor dwarf star in the Galactic bulge
T. Bensby, S. Feltzing, J. A. Johnson +6
Measurements based on a large number of red giant stars suggest a broad metallicity distribution function (MDF) for the Galactic bulge, centered on [Fe/H]=-0.1. However, recently,…
