Large amplitude periodic outbursts and long period variables in the VVV VIRAC2- database
Zhen Guo, P. W. Lucas, L. C. Smith +13
The VISTA Variables in the Via Lactea (VVV) survey obtained near-infrared photometry toward the Galactic bulge and the southern disc plane for a decade (2010 - 2019). We designed a…
Variable stars in the VVV globular clusters. II. NGC6441, NGC6569, NGC6626 (M28), NGC6656 (M22), 2MASS-GC02, and Terzan10
Javier Alonso-García, Leigh C. Smith, Márcio Catelan +18
The Galactic globular clusters (GGCs) located in the inner regions of the Milky Way suffer from high extinction that makes their observation challenging. The VVV survey provides a…
Analysis of physical processes in eruptive YSOs with near infrared spectra and multi-wavelength light curves
Zhen Guo, P. W. Lucas, C. Contreras Peña +11
The decade-long Vista Variables in the Via Lactea (VVV) survey has detected numerous highly variable young stellar objects (YSOs). We present a study of 61 highly variable VVV YSOs…
Discovery of a mid-infrared protostellar outburst of exceptional amplitude
P. W. Lucas, J. Elias, S. Points +12
We report the discovery of a mid-infrared outburst in a Young Stellar Object (YSO) with an amplitude close to 8 mag at 4.6 m. WISEA J142238.82-611553.7 is one of 23…
VVV-WIT-01: highly obscured classical nova or protostellar collision?
P. W. Lucas, D. Minniti, A. Kamble +18
A search of the first Data Release of the VISTA Variables in the Via Lactea (VVV) Survey discovered the exceptionally red transient VVV-WIT-01 (). It peaked before March…
Short and long term near-infrared spectroscopic variability of eruptive protostars from VVV
Zhen Guo, P. W. Lucas, C. Contreras Peña +7
Numerous eruptive variable young stellar objects (YSOs), mostly Class I systems, were recently detected by the near-infrared Vista Variables in the Via Lactea (VVV) survey. We pres…
