Variable Stars in the Quintuplet stellar cluster with the VVV Survey
C. Navarro Molina, J. Borissova, M. Catelan +7
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 vici…
Near-infrared photometry and spectroscopy of the low Galactic latitude globular cluster 2MASS-GC03
Julio A. Carballo-Bello, S. Ramirez Alegria, J. Borissova +12
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 Observat…
Infrared spectroscopy of eruptive variable protostars from VVV
C. Contreras Peña, P. W. Lucas, R. Kurtev +11
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 c…
A population of eruptive variable protostars in VVV
C. Contreras Peña, P. W. Lucas, D. Minniti +10
We present the discovery of 816 high amplitude infrared variable stars ( 1 mag) in 119 deg of the Galactic midplane covered by the Vista Variables in the Via Lact…
