Abstract (from CDS):

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.
