Chemical evolution of the Galactic bulge as traced by microlensed dwarf and subgiant stars. VI. Age and abundance structure of the stellar populations in the central sub-kpc of the Milky Way
T. Bensby, S. Feltzing, A. Gould +29
We present a detailed elemental abundance study of 90 F and G dwarf, turn-off and subgiant stars in the Galactic bulge. Based on high-resolution spectra acquired during gravitation…
Insights into the chemical composition of the metal-poor Milky Way halo globular cluster NGC 6426
M. Hanke, A. Koch, C. J. Hansen +1
We present our detailed spectroscopic analysis of the chemical composition of four red giant stars in the halo globular cluster NGC 6426. We obtained high-resolution spectra using…
Something borrowed, something blue: The nature of blue metal-poor stars inferred from their colours and chemical abundances
C. J. Hansen, P. Jofre, A. Koch +2
Blue metal-poor stars (BMPs) are main sequence stars that appear bluer and more luminous than normal turnoff stars. They were originally singled out by using B-V and U-B colour cut…
The GIRAFFE Inner Bulge Survey (GIBS) III. Metallicity distributions and kinematics of 26 Galactic bulge fields
M. Zoccali, S. Vasquez, O. A. Gonzalez +9
Several recent studies have demonstrated that the Galactic bulge hosts two components with different mean metallicities, and possibly different spatial distribution and kinematics.…
The GIRAFFE Inner Bulge Survey (GIBS). I. Survey Description and a kinematical map of the Milky Way bulge
M. Zoccali, O. A. Gonzalez, S. Vasquez +10
The Galactic bulge is a massive, old component of the Milky Way. It is known to host a bar, and it has recently been demonstrated to have a pronounced boxy/peanut structure in its…
Mapping the X-Shaped Milky Way Bulge
Roberto K. Saito, Manuela Zoccali, Andrew McWilliam +3
We analyzed the distribution of the RC stars throughout Galactic bulge using 2MASS data. We mapped the position of the red clump in 1 sq.deg. size fields within the area |l|<=8.5de…
