Spectroscopy of Red Giants in the LMC Bar: Abundances, Kinematics, and the Age-Metallicity Relation
Andrew A. Cole, E. Tolstoy, J. S. Gallagher +1
We report metallicities and radial velocities derived from spectra at the near-infrared calcium triplet for 373 red giants in a 200 square arcminute area at the optical center of t…
Abundances as Tracers of the Formation and Evolution of (Dwarf) Galaxies
Eline Tolstoy
This aims to be an overview of what detailed observations of individual stars in nearby dwarf galaxies may teach us about galaxy evolution. This includes some early results from th…
Two distinct ancient components in the Sculptor Dwarf Spheroidal Galaxy: First Results from DART
Eline Tolstoy, M. J. Irwin, A. Helmi +14
We have found evidence for the presence of two distinct ancient stellar components (both geq 10 Gyr old) in the Sculptor dwarf spheroidal galaxy. We used the ESO Wide Field Imager…
Stellar Chemical Signatures And Hierarchical Galaxy Formation
K. A. Venn, M. Irwin, M. D. Shetrone +3
ABRIDGED: To compare the chemistries of stars in the Milky Way dSph galaxies with stars in the Galaxy, we have compiled a large sample of Galactic stellar abundances from the liter…
First Stellar Abundances in the Dwarf Irregular Galaxy Sextans A
Andreas Kaufer, Kim A. Venn, Eline Tolstoy +2
We present the abundance analyses of three isolated A-type supergiant stars in the dwarf irregular galaxy Sextans A from high-resolution spectra the UVES spectrograph at the VLT. D…
