Young Stellar Clusters Containing Massive Young Stellar Objects in the VVV Survey
J. Borissova, S. Ramírez Alegría, J. Alonso +17
The purpose of this research is to study the connection of global properties of eight young stellar clusters projected in the Vista Variables in the Via Lactea (VVV) ESO Large Publ…
Massive open star clusters using the VVV survey III: A young massive cluster at the far edge of the Galactic bar
S. Ramírez Alegría, J. Borissova, A. N. Chené +14
Context: Young massive clusters are key to map the Milky Way's structure, and near-IR large area sky surveys have contributed strongly to the discovery of new obscured massive stel…
Time-Series BVI Photometry for the Globular Cluster NGC 6981 (M72)
P. Amigo, P. B. Stetson, M. Catelan +2
We present new BVI photometry of the globular cluster NGC 6981 (M72), based mostly on ground-based CCD archive images. We present a new color-magnitude diagram (CMD) that reaches a…
NGC5694: another extra-galactic globular cluster
A. Mucciarelli, M. Bellazzini, M. Catelan +5
We discuss the chemical composition of six giant stars of the outer Halo globular cluster NGC5694, through the analysis of UVES@FLAMES high-resolution spectra. The cluster has an a…
Multiple populations in Galactic globular clusters: a survey in the Strömgren system
J. Alonso-García, M. Catelan, P. Amigo +10
We are coming to believe that stellar populations in globular clusters are not as simple as they were once thought to be. A growing amount of photometric and spectroscopic evidence…
Disentangling multiple stellar populations in globular clusters using the Strömgren system
J. Alonso-García, M. Catelan, P. Amigo +10
An increasing amount of spectroscopic and photometric evidence is showing that the stellar populations of globular clusters are not as simple as they have been considered for many…
