At 13 Myr, h and chi Persei bridge the gap between T Tauri disks and older debris disks, probing an important transition for disk evolution and planet formation processes. These clusters are a unique laboratory at this age to provide insight into planet formation time-scales, disk transition time-scales, and to constrain disk evolutionary models. We propose a deep IRAC survey to examine the behavior of the excess fraction. We will probe how disks evolve as a function of stellar mass down to subsolar mass limits during the critical age when optically thick T Tauri disks transition to optically thin debris disks.
