VISTA Variables in the Via Lactea (VVV): The public ESO near-IR variability survey of the Milky Way
D. Minniti, P. W. Lucas, J. P. Emerson +63
We describe the public ESO near-IR variability survey (VVV) scanning the Milky Way bulge and an adjacent section of the mid-plane where star formation activity is high. The survey…
Hierarchical structures in the Large and Small Magellanic Clouds
Charles Bonatto, Eduardo Bica
We investigate the degree of spatial correlation among extended structures in the LMC and SMC. To this purpose we work with sub-samples characterised by different properties such a…
Open cluster survival within the solar circle: Teutsch145 and Teutsch146
Charles Bonatto, Sergio Ortolani, Beatriz Barbuy +1
Teutsch145 and Teutsch146 are shown to be open clusters (OCs) orbiting well inside the Solar circle, a region where several dynamical processes combine to disrupt most OCs on a tim…
Astrophysical parameters of 14 open clusters projected close to the Galactic plane
Denilso Camargo, Charles Bonatto, Eduardo Bica
Astrophysical parameters (\textit{age, reddening, distance, core and cluster radii}) of 14 open clusters (OCs) projected close to the Galactic plane are derived with 2MASS photomet…
The nature of the young and low-mass open clusters Pismis5, vdB80, NGC1931 and BDSB96
Charles Bonatto, Eduardo Bica
We investigate the nature of 4 young and low-mass open clusters (OCs) located in the and quadrants with near-IR 2MASS photometry (errors mag). After field…
The globular cluster NGC 6642: Evidence for a depleted mass function in a very old cluster
E. Balbinot, B. X. Santiago, E. Bica +1
We present photometry for the globular cluster NGC 6642 using the F606W and F814W filters with the ACS/WFC third generation camera on board of Hubble Space Telescope. The Colour Ma…
