VISTA Variables in the Via Lactea (VVV): The public ESO near-IR variability survey of the Milky Way

We describe the public ESO near-IR variability survey (VVV) scanning the Milky Way bulge and an adjacent section of the mid-plane where star formation activity is high. The survey will take 1929 h of observations with the 4-m VISTA telescope during 5 years (2010-2014), covering ∼10 9 point sources a...

The survey will take 1929 h of observations with the 4-m VISTA telescope during 5 years (2010-2014), covering ∼10 9 point sources across an area of 520 deg 2 , including 33 known globular clusters and ∼350 open clusters.
