Resumen

The search for high-amplitude infrared variable stars with the Vista Variables in the Via Lactea (VVV) survey yields 106 likely YSOs with eruptive light curves, increasing the number of known eruptive variable YSOs by a factor of about 5. Spectroscopic follow-up confirms 19 objects as new additions to the variable class. These differ from FUors and EXors as they are generally optically obscured systems at earlier stages of evolution, show 1 to 4 year duration of the outbursts and have a mixture of the spectroscopic characteristics of both subclasses.
