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.…
