X-ray Follow-up to the Deep NIR Monitoring Campaign of CygOB7

We have recently participated in an intense nearIR (NIR) monitoring campaign ofthe embedded star forming region Cygnus OB7 covering over 100,000 stars brighterthan K20. It has revealed the region is rich in protostars, eruptive T Tauristars and ClassvirgulII objects. We have discovered periodic and aperiodic NIRvariability seen among the Class I and Class II objects, indicative of variableaccretion and quasiinstability of the inner hole. Further, NIR Class. canchange between observations. We seek a 80virgulks XMMNewton observation to compareX ray luminosity to NIR variability of the known Class 0II sources, eruptive TTauri stars and eclipsing binaries as well as to identify new ClassvirgulII and ClassIII sources in a very young active region. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
