Near-infrared spectra of 133 red giant stars from 10 Galactic open clusters and two Galactic globular clusters spanning 2.2dex in metallicity and 11Gyr in age are presented. We combine this sample with 10 clusters from Cole and collaborators to investigate the CaII triplet line strengths and their relation to cluster metallicity and position along the red giant branch. We show that characterizing the stellar surface gravity using Ks-band photometry (relative to the horizontal branch) taken from… Expand
Homogeneous metallicities and radial velocities for Galactic globular clusters: First CaT metallicities for twenty clusters
Well determined radial velocities and abundances are essential for analyzing the properties of the globular cluster system of the Milky Way. However more than 50% of these clusters have noExpand
TOWARD THE GENERAL RED GIANT BRANCH SLOPE-METALLICITY-AGE CALIBRATION. I. METALLICITIES, AGES, AND KINEMATICS FOR EIGHT LARGE MAGELLANIC CLOUD CLUSTERS

Homogeneous metallicities and radial velocities for Galactic globular clusters
Although the globular clusters in the Milky Way have been studied for a long time, a significant fraction of them lack homogeneous metallicity and radial velocity measurements. In an earlier paper weExpand
Radial velocity and metallicity of the globular cluster IC4499 obtained with AAOmega

Aims. We present a new calibration of the calcium II triplet equivalent widths versus [Fe/H], constructed upon K giant stars in the Galactic bulge. This calibration will be used to derive ironExpand
ASTEROSEISMIC STUDY ON CLUSTER DISTANCE MODULI FOR RED GIANT BRANCH STARS IN NGC 6791 AND NGC 6819
Stellar distance is an important basic parameter in stellar astrophysics. Stars in a cluster are thought to be formed coevally from the same interstellar cloud of gas and dust; therefore, they areExpand
