Abstract

We present the results of an infrared imaging survey of two clusters in the Cep OB2 Association, Tr 37 and NGC 7160, using the IRAC and MIPS instruments on board the Spitzer Space Telescope. Our observations cover the wavelength range from 3.6 to 24 mu m, allowing us to detect disk emission over a typical range of radii similar to 0.1 to similar to 20AU from the central star. In Tr 37, with an age of about 4 Myr, about 48% of the low- mass stars exhibit detectable disk emission in the IRAC bands. Roughly 10% of the stars with disks may be "transition'' objects, with essentially photospheric fluxes at wavelengths
