New variable stars discovered in the fields of three Galactic open clusters using the VVV Survey
Tali Palma, Dante Minniti, Istvan Dékány +5
This project is a massive near-infrared (NIR) search for variable stars in highly reddened and obscured open cluster (OC) fields projected on regions of the Galactic bulge and disk…
Massive open star clusters using the VVV survey V. Young clusters with an OB stellar population
S. Ramírez Alegría, J. Borissova, A. -N. Chené +6
The ESO public survey VISTA Variables in the Vía Láctea (VVV) has contributed with deep multi-epoch photometry of the Galactic bulge and the adjacent part of the disk over 526 squa…
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…
A not so massive cluster hosting a very massive star
S. Ramírez Alegría, A. -N. Chené, J. Borissova +4
We present the first physical characterization of the young open cluster VVV CL041. We spectroscopically observed the cluster main-sequence stellar population and a very-massive st…
Discovery of a young and massive stellar cluster: Spectrophotometric near-infrared study of Masgomas-1
S. Ramírez Alegría, A. Marín-Franch, A. Herrero
Context: Recent near-infrared data have contributed to the discovery of new (obscured) massive stellar clusters and massive stellar populations in previously known clusters in our…
Near-infrared study of the stellar population of Sh2-152
S. Ramírez Alegría, A. Herrero, A. Marín-Franch +5
Context: The discovery of new massive star clusters and massive stellar populations in previously known clusters in our Galaxy by means of infrared studies has changed our view of…
