Kinematic Structure in the Galactic Halo at the North Galactic Pole: RR Lyrae and BHB Stars show different kinematics
T. D. Kinman, C. Cacciari, A. Bragaglia +2
Space motions are given for 38 RR Lyrae (RRL) stars and 79 blue horizontal branch (BHB) stars in a ~200 deg2 area around the North Galactic Pole (NGP) using a homogeneous distance…
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…
BVI photometry of the very old open cluster Berkeley 17
Angela Bragaglia, Monica Tosi, Gloria Andreuzzi +1
We have obtained BVI CCD imaging of Berkeley 17, an anticentre open cluster that competes with NGC 6791 as the oldest known open cluster. Using the synthetic colour magnitude diagr…
The old anticentre open cluster Berkeley 32: membership and fundamental parameters
V. D'Orazi, A. Bragaglia, M. Tosi +2
We have obtained medium-low resolution spectroscopy and BVI CCD imaging of Berkeley 32, an old open cluster which lies in the anticentre direction. From the radial velocities of 48…
The metallicity of the old open cluster NGC 6791
Raffaele Gratton, Angela Bragaglia, Eugenio Carretta +1
We have observed four red clump stars in the very old and metal-rich open cluster NGC 6791 to derive its metallicity, using the high resolution spectrograph SARG mounted on the TNG…
