Title: Disk evolution in Cep OB2 clusters Tr37 and NGC7160

Abstract: The evolution of protoplanetary disks through the likely epoch of (giant) planet formation is poorly understood, in part because of a lack of good samples of young stars in the age range 3-10 Myr. We propose JHK photometry with Flamingos using the KPNO 2.1m telescope to search for infrared excess emission due to disks in members of two open clusters belonging to Cep OB2 region, NGC7160 and Tr37. Our previous observational work has indicated that the ages of these clusters are approximately 10 and 3-5 Myr, respectively, so they are ideal for studying disk evolution. The proposed near-infrared observations constitute the initial stage of a longer-term effort to investigate disk emission in these clusters.
