A population of eruptive variable protostars in VVV
(2017-03-01)
We present the discovery of 816 high amplitude infrared variable stars (Delta Ks >1 mag) in 119 deg^2 of the Galactic midplane covered by the Vista Variables in the Via Lactea (VVV) survey. Almost all are new discoveries ...
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 ...
