Near-IR properties of 24 Globular Clusters in the Galactic Bulge
E. Valenti, F. R. Ferraro, L. Origlia
We present near-IR Color-Magnitude Diagrams and physical parameters for a sample of 24 Galactic Globular Clusters toward the Bulge direction. In this paper we discuss the propertie…
Na-O Anticorrelation And HB. III. The abundances of NGC 6441 from FLAMES-UVES spectra
R. G. Gratton, S. Lucatello, A. Bragaglia +4
The aim of the present work is to determine accurate metallicities for a group of red giant branch stars in the field of the bulge Globular Cluster NGC 6441. This is the third pape…
The Red Giant Branch in Near-Infrared Colour-Magnitude Diagrams. II: The luminosity of the Bump and the Tip
E. Valenti, F. R. Ferraro, L. Origlia
We present new empirical calibrations of the Red Giant Branch (RGB) Bump and Tip based on a homogeneous near-Infrared database of 24 Galactic Globular Clusters. The luminosities of…
The Red Giant Branch in the Near-Infrared Colour-Magnitude Diagrams. I: The calibration of photometric indices
E. Valenti, F. R. Ferraro, L. Origlia
We present new high-quality near-infrared photometry of 10 Galactic Globular Clusters spanning a wide metallicity range (-2.12<[Fe/H]<-0.49): five clusters belong to the Halo (name…
TNG Near-IR Photometry of five Galactic Globular Clusters
E. Valenti, F. R. Ferraro, S. Perina +1
We present near--infrared J and K observations of giant stars in five metal-poor Galactic Globular Clusters (namely M3, M5, M10, M13 and M92) obtained at the Telescopio Nazionale G…
