We present the analysis of seven-band (1.2 to 8 μm) ground- and space-based imaging of the NGC 7129 young stellar cluster from FLAMINGOS on MMT, Two Micron All Sky Survey (2MASS), and the Infrared Array Camera (IRAC) on Spitzer . An analysis of the H -[4.5] versus J - H colors reveals 84 objects with circumstellar disks. Of these, 42 are located within the cluster core, a 0.5 pc (100'') radius region of enhanced stellar surface density. From a luminosity- and extinction-limited sample of the stars within the cluster core boundary we have determined that 54% ± 14% have circumstellar disks. Finally, we report the detection of several resolved outflows in the IRAC 4.5 μm mosaic.
