Title: Characterizing Variable Young Stars in NGC 2264
Abstract: In December 2011 we carried out an unprecedented 30 days of continuous photometric monitoring on the ~3 Myr cluster NGC 2264 using the \em Corot and \em Spitzer space telescopes, along with additional data from \em Chandra, \em MOST, and several ground-based observatories. The resulting high-precision, high-cadence lightcurves display a stunning array of variability in young stellar objects (``YSOs'') at wavelengths from X-ray through the mid-infrared. These data are a vital contribution to the understanding of YSO variability behavior and its connection to physical phenomena, including dynamics of the inner disk; they constitute a legacy dataset that will be valuable for years to come. What is needed now is a dedicated spectroscopic follow-up campaign to characterize the global properties of our sample and thereby correlate the observed variability with parameters such as temperature and extinction. We propose here to complement our extensive multiwavelength photometric monitoring dataset with a large set of low- resolution spectra from the WIYN/Hydra multi-object spectrograph.
