Kinematics of the disk population in the GAIA era
G. Bertelli, A. Vallenari, S. Pasetto +1
GAIA data will create a precise 3-dimensional map of the Galaxy, providing positional information, radial velocities, luminosity, temperature and chemical composition of a represen…
Cluster formation in the LMC
A. Vallenari, A. Moretti, E. V. Held +2
In this work we present preliminary results concerning the properties of about 50 clusters and associations located in a densely populated region at the Southern edge of the supers…
The Field population towards NGC 6553
A. Vallenari, S. Ortolani
We analyze the colour magnitude diagram of the field population in the direction of the bulge cluster NGC 6553 to discuss the stellar field component projected towards the cluster.…
Near-infrared photometry of the intermediate age open clusters IC 166 and NGC 7789
Antonella Vallenari, Giovanni Carraro, Andrea Richichi
We present and discuss new photometric data obtained with an IR camera in the J and K pass-bands for the intermediate age open clusters IC 166 (936 stars in total) and NGC 7789 (10…
Near IR photometry of the old open clusters Berkeley 17 and Berkeley 18. Probing the age of the galactic disc
Giovanni Carraro, Antonella Vallenari, Leo Girardi +1
We report on near IR ( and bands) observations of two regions centered on the old open clusters Berkeley~17 and Berkeley~18, for which only optic…
Interacting star clusters in the LMC - Overmerging problem solved by cluster group formation
S. Leon, G. Bergond, A. Vallenari
We present the tidal tail distributions of a sample of candidate binary clusters located in the bar of the Large Magellanic Cloud (LMC). One isolated cluster, SL 268, is presented…
