A comparative analysis of the observed white dwarf cooling sequence from globular clusters
Fabíola Campos, P. Bergeron, A. D. Romero +8
We report our study of features at the observed red end of the white dwarf cooling sequences for three Galactic globular clusters: NGC\,6397, 47\,Tucanae and M\,4. We use deep colo…
Characterizing star cluster formation with WISE: 652 newly found star clusters and candidates
Denilso Camargo, Eduardo Bica, Charles Bonatto
We report the discovery of 652 star clusters, stellar groups and candidates in the Milky Way with WISE. Most of the objects are projected close to Galactic Plane and are embedded c…
A Dynamical Evolution Study of 40 2MASS Open Clusters
Orhan Güneş, Yüksel Karataş, Charles Bonatto
We investigate the dynamical evolution of 40 open clusters (OCs) by means of their astrophysical parameters derived from field-decontaminated 2MASS photometry. We find a bifurcatio…
Massive open star clusters using the VVV survey IV. WR 62-2, a new very massive star in the core of the VVV CL041 cluster
A. -N. Chené, S. Ramírez Alegría, J. Borissova +8
Context The ESO Public Survey VISTA Variables in the Vía Láctea (VVV) provides deep multi-epoch infrared observations for an unprecedented 562 sq. degrees of the Galactic bulge and…
Bridge over troubled gas: clusters and associations under the SMC and LMC tidal stresses
E. Bica, B. Santiago, C. Bonatto +5
We obtained SOAR telescope B and V photometry of 14 star clusters and 2 associations in the Bridge tidal structure connecting the LMC and SMC. These objects are used to study the f…
Photometry and dynamics of the minor mergers AM\,1228-260 and AM\,2058-381
J. A. Hernandez-Jimenez, M. G. Pastoriza, C. Bonatto +3
We investigate interaction effects on the dynamics and morphology of the galaxy pairs AM\,2058-381 and AM\,1228-260. This work is based on images and long-slit spectra obtaine…
