A multicolor CCD photometric study of the open clusters NGC 2866, Pismis 19, Westerlund 2, ESO96-SC04, NGC 5617 and NGC 6204
Giovanni Carraro, Ulisse Munari
Accurate and deep BVI CCD photometry is presented for the core regions of six southern compact open clusters (supplemented in one case by U and R bands). These clusters generally h…
The old open clusters Saurer A, B and C revisited
Giovanni Carraro, Gustavo Baume
We report on deep (V 24.0) CCD photometry of 3 fields centered in the regions of the old open clusters Saurer A, B and C. In the case of Saurer A, which is considere…
A survey of Probable Open Cluster Remnants in the Galactic Disk
Sandro Villanova, Giovanni Carraro, Raul de la Fuente Marcos
We present preliminary results of an ongoing survey to probe the physical nature of a sample of open clusters (POCRs, Bica et al. 2001) believed to be in an advanced stage of dynam…
A study of the two northern open clusters NGC 1582 and NGC 1663
Gustavo Baume, Sandro Villanova, Giovanni Carraro
We present CCD observations obtained in the field of the previously unstudied northern open clusters NGC 1582 and NGC 1663. For the former, we also provide high-resoluti…
Using globular clusters to test gravity in the weak acceleration regime
Riccardo Scarpa, Gianni Marconi, Roberto Gilmozzi
We have carried out a study of the velocity dispersion of the stars in the outskirts of the globular cluster Omega Centauri, finding that the velocity dispersion remains constant a…
NGC 1883: a neglected intermediate-age open cluster located in the outskirts of the Galactic disk
Giovanni Carraro, Gustavo Baume, Sandro Villanova
We report on CCD photometry of a field centered in the region of the open cluster NGC 1883 down to V=21. This cluster has never been studied insofar, and we provide for the f…
