Abstract:
Knowledge of the stellar content near the Sun is important for a broad
range of topics ranging from the search for planets to the study of
Milky Way (MW) structure. The most powerful method for identifying
potentially nearby stars is proper motion (PM) surveys. All old
optical surveys avoid, or are at least substantially incomplete, near
the Galactic plane. The depth and breadth of the 'VISTA Variables in
Via Lactea' (VVV) near-IR survey significantly improves this
situation. Taking advantage of the VVV survey data base, we have
measured PMs in the densest regions of the MW bulge and southern plane
in order to complete the census of nearby objects. We have developed a
custom PM pipeline based on VVV catalogues from the Cambridge
Astronomy Survey Unit, by comparing the first epoch of JHKs with the
multi-epoch Ks bands acquired later. Taking advantage of the large
time baseline between the Two Micron All Sky Survey (2MASS) and the
VVV observations, we also obtained 2MASS-VVV PMs. We present a near-IR
PM catalogue for the whole area of the VVV survey, which includes 3003
moving stellar sources. All of these have been visually inspected and
are real PM objects. Our catalogue is in very good agreement with the
PM data supplied in IR catalogues outside the densest zone of the MW.
The majority of the PM objects in our catalogue are nearby M-dwarfs,
as expected. This new data base allows us to identify 57 common PM
binary candidates, among which are two new systems within 30 pcof the
Sun.
Description:
A catalogue of 3003 high proper motion stars projected on the area of
the Vista Variables en via Lactea NIR survey. The positions of the
first and the last VVV epochs as well as the 2MASS positions of the
majority of the catalogue objects are given. The catalogue also
contains photometrical data for these 3003 nearby stars in ZYJHKs
filters. The proper motions are calculated one using the VVV only data
and VVV-2MASS positions.
