      Peña, C. Contreras; Lucas, P. W.; Kurtev, R.; Minniti, D.; Garatti, A. Caratti o; Marocco, F.; Thompson, M. A.; Froebrich, D.; Kumar, N.; Stimson, W.; Molina, C. Navarro; Borissova, J.; Gledhill, T.; Terzi, R. (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 ...

    • A population of eruptive variable protostars in VVV 

      Peña, C. Contreras; Lucas, P. W.; Minniti, D.; Kurtev, R.; Stimson, W.; Molina, C. Navarro; Borissova, J.; Kumar, N.; Thompson, M. A.; Gledhill, T.; Terzi, R.; Froebrich, D.; Garatti, A. Caratti o (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 ...
