A near-infrared stellar atlas of the Galactic plane from the VVVX survey
Javier Alonso-García, Maren Hempel, Roberto K. Saito +12
The VISTA Variables in the Via Lactea eXtended (VVVX) ESO public survey observed the Galactic plane and the outer Galactic bulge in the near-infrared to mitigate the effects of ext…
Variable stars in the VVV globular clusters III. RR Lyrae stars in the inner Galactic globular clusters
Javier Alonso-García, Leigh C. Smith, Jason L. Sanders +13
High reddening near the Galactic plane hampers observations and proper characterization of the globular clusters (GCs) located toward the inner regions of the Milky Way. The VISTA…
VIRAC2: NIR Astrometry and Time Series Photometry for 500M+ Stars from the VVV and VVVX Surveys
Leigh C. Smith, Philip W. Lucas, Sergey E. Koposov +11
We present VIRAC2, a catalogue of positions, proper motions, parallaxes and , , , , and near-infrared photometric time series of 545 346 537 unique stars. The cat…
The globular cluster VVV CL002 falling down to the hazardous Galactic centre
D. Minniti, N. Matsunaga, J. G. Fernandez-Trincado +15
Context. The Galactic centre is hazardous for stellar clusters because of the strong tidal force. Supposedly, many clusters were destroyed and contributed stars to the crowded stel…
Mapping the stellar age of the Milky Way bulge with the VVV. II. Deep JKs catalogs release based on PSF photometry
F. Surot, E. Valenti, S. L. Hidalgo +6
The bulge represents the best compromise between old and massive Galactic component, and as such its study is a valuable opportunity to understand how the bulk of the Milky Way for…
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…
New galactic star clusters discovered in the VVV survey. Candidates projected on the inner disk and bulge
J. Borissova, A. -N. Chené, S. Ramírez Alegría +21
VISTA Variables in the Vía Láctea (VVV) is one of six ESO Public Surveys using the 4 meter Visible and Infrared Survey Telescope for Astronomy (VISTA). The VVV survey covers the Mi…
Milky Way Demographics with the VVV Survey II. Color Transformations and Near-Infrared Photometry for 136 Million Stars in the Southern Galactic Disk
M. Soto, R. Barba, G. Gunthardt +18
The new multi-epoch near-infrared VVV survey (VISTA Variables in the Via Lactea) is sampling 562 sq. deg of the Galactic bulge and adjacent regions of the disk. Accurate astrometry…
