Title: Synoptic Monitoring of YSOs in Four Young Custers with FLAMINGOS and Spitzer

Abstract: We propose to use FLAMINGOS on the KPNO 2.1m to obtain synoptic monitoring over a 10 night period at J and Ks bands of > 100 Class I and II young stellar objects in the dense cores of four nearby, star- forming clusters: L1688, Serpens Main, Serpens South, and IRAS 20050+2720. These data will be used to complement time-series photometry we will be obtaining with IRAC on the Spitzer Space Telescope as part of a recently approved "Exploration Science" program to be carried out during the Spitzer warm mission. 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, and therefore, shed new light on the processes involved in accreting matter onto the youngest stars (beyond the realm of steady-state accretion from axially symmetric disks).
