A search for spectroscopic binaries in the galactic globular cluster M4. Based on 5973 individual spectra collected at VLT
V. Sommariva, G. Piotto, M. Rejkuba +4
We present a large multi-epoch high resolution spectroscopic investigation for the search of binary candidates in the Galactic Globular Cluster (GGC) M4. The aim of our work is the…
Tombaugh 2: The First Open Cluster with a Significant Abundance Spread or Embedded in a Cold Stellar Stream?
P. M. Frinchaboy, A. F. Marino, S. Villanova +3
We present new abundances and radial velocities for stars in the field of the open cluster Tombaugh 2, which has been suggested to be associated with the Galactic Anticenter Stella…
Spectroscopic and Photometric evidence of two stellar populations in the Galactic Globular Cluster NGC6121 (M4)
A. F. Marino, S. Villanova, G. Piotto +4
AIMS. We present abundance analysis based on high resolution spectra of 105 isolated red giant branch (RGB) stars in the Galactic Globular Cluster NGC 6121 (M4). Our aim is to stud…
Ground-based CCD astrometry with wide field imagers. II. A star catalogue for M67: [email protected] MPG/ESO astrometry, FLAMES@VLT radial velocities
R. K. S. Yadav, L. R. Bedin, G. Piotto +7
The solar-age open cluster M67 (C0847+120, NGC2682) is a touchstone in studies of the old Galactic disk. Despite its outstanding role, the census of cluster membership for M67 at f…
The old open cluster NGC 2112: updated estimates of fundamental parameters based on a membership analysis
Giovanni Carraro, Sandro Villanova, Pierre Demarque +2
We report on a new, wide field (), multicolor (), photometric campaign in the area of the nearby old open cluster NGC 2112. At the same time,…
