BS196: an old star cluster far from the SMC main body
E. Bica, J. F. C. Santos, A. A. Schmidt
We present B and V photometry of the outlying SMC star cluster BS196 with the 4.1-m SOAR telescope. The photometry is deep (to V~25) showing ~3 mag below the cluster turnoff point…
Spectral evolution of star clusters in the Large Magellanic Cloud: I. Blue concentrated clusters in the age range 40-300 Myr
J. F. C. Santos, J. J. Claria, A. V. Ahumada +3
Integrated spectroscopy of a sample of 17 blue concentrated Large Magellanic Cloud (LMC) clusters is presented and its spectral evolution studied. The spectra span the range ~3600-…
Structure and stellar content analysis of the open cluster M11 with 2MASS photometry
J. F. C. Santos, C. Bonatto, E. Bica
An overall analysis of the structure and stellar content of M11 is presented, thanks to the wide-angle 2MASS spatial coverage. We derive photometric and structural parameters and d…
Integrated spectral analysis of 18 concentrated star clusters in the Small Magellanic Cloud
A. E. Piatti, J. F. C. Santos, J. J. Claria +3
We present in this study flux-calibrated integrated spectra in the range 3600-6800A for 18 concentrated SMC clusters. Cluster reddening values were estimated by interpolation betwe…
Spatial dependence of 2MASS luminosity and mass functions in the old open cluster NGC 188
C. Bonatto, E. Bica, J. F. C. Santos
Luminosity and mass functions in the old open cluster NGC 188 are analysed by means of J and H 2MASS photometry. Within the uncertainties, the observed projected radial density pro…
Ages and metallicities of star clusters: new calibrations and diagnostic diagrams from visible integrated spectra
J. F. C. Santos, A. E. Piatti
We present homogeneous scales of ages and metallicities for star clusters from very young objects, through intermediate-age ones up to the oldest known clusters. All the selected c…
