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.
