Title: Synoptic Monitoring of YSOs in Orion, NGC2264 and Mon R2 with Flamingos and Spitzer

Abstract: We propose to use Flamingos on the KPNO 2.1m to obtain synoptic monitoring at J- and Ks-bands of Class I and II young stellar objects in the Orion Nebula Cluster and in two smaller star-forming cores, over a 10 night period. These data will be used to complement time-series photometry we will be obtaining simultaneously with IRAC on the Spitzer Space Telescope. The goal of this program is to use the multi- wavelength photometric monitoring data to determine the physical mechanisms responsible for the near-IR and mid-IR variability of these YSOs. These observations should shed new light on the processes involved in the formation and evolution of circumstellar (planet- forming) disks and on the accretion of matter from these disks onto their "host" stars.
