Title: Flamingos Spectroscopy of Young Stellar Clusters: Tracing the Initial Configuration and Early Evolution

Abstract: We are executing a combined ground-based near-IR and Spitzer mid-IR survey of young stellar clusters within 1 kpc of the sun, to understand the initial configuration of young stellar clusters, their dynamical evolution as they disrupt their natal clouds, and the effect of the cluster environment on star and planet formation. We propose here Flamingos multislit spectra of three clusters which we are intensively studying using near and mid-IR photometry: IRAS 20050+2720, GGD 12-15 and NGC 7129. This program will determine ages for the clusters, and allow us to look for variations in the mass function and accretion properties between the clusters and within the individual clusters. The ages will have significant implications for the role clustering may play in the tidal disruption of proto- planetary disks.
