Stellar Variability in the VVV survey
M. Catelan, D. Minniti, P. W. Lucas +34
The Vista Variables in the Vía Láctea (VVV) ESO Public Survey is an ongoing time-series, near-infrared (IR) survey of the Galactic bulge and an adjacent portion of the inner disk,…
VVV Survey Near-Infrared Photometry of Known Bulge RR Lyrae stars: the Distance to the Galactic Center and Absence of a Barred Distribution of the Metal-Poor Population
I. Dékány, D. Minniti, M. Catelan +4
We have combined optical and near-infrared data of known RR Lyrae (RRL) stars in the bulge in order to study the spatial distribution of its metal-poor component by measuring preci…
Searching for variable stars in the VVV globular clusters
Javier Alonso-García, István Dékány, Márcio Catelan +2
The VVV is currently surveying the central regions of the Milky Way at near-infrared wavelengths, including 36 known Galactic globular clusters. We already have data in several fil…
