Infrared spectroscopy of eruptive variable protostars from VVV
(2017-03-01)
In a companion work (Paper I) we detected a large population of highly variable Young Stellar Objects (YSOs) in the Vista Variables in the Via Lactea (VVV) survey, typically with class I or flat spectrum spectral energy ...
VVV High proper motion stars I. The catalogue of bright Ks stars
(2017-01-01)
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 structure. The most powerful method for identifying potentially nearby ...
Variable Stars in the Quintuplet stellar cluster with the VVV Survey
(2016-10-21)
The Quintuplet cluster is one of the most massive star clusters in the Milky Way, situated very close to the Galactic center. We present a new search for variable stars in the vicinity of the cluster, using the five-year ...
Near-infrared photometry and spectroscopy of the low Galactic latitude globular cluster 2MASS-GC03
(2016-10-11)
We present deep near-infrared photometry and spectroscopy of the globular cluster 2MASS-GC03 projected in the Galactic disk using MMIRS on the Clay telescope (Las Campanas Observatory) and VISTA Variables in the Via Lactea ...
Probing the Dragonfish star-forming complex: : the ionizing population of the young massive cluster Mercer 30
(2016-05-01)
The Dragonfish Nebula has been recently claimed to be powered by a superluminous but elusive OB association. Instead, systematic searches in near-infrared photometric surveys have found many other cluster candidates on ...
VVV High Proper Motion Survey
(2013-10-15)
Here we present survey of proper motion stars towards the Galactic Bulge and an adjacent plane region base on VISTA-VVV data. The searching method based on cross-matching photometric Ks-band CASU catalogs. The most interesting ...
