Title: Monitoring Mega-Year T Tauri Stars With Disks: Which Ones Blow?

Abstract: We propose to use the KPNO 0.9m to obtain BVR photometry of T Tauri stars with known disk morphologies to identify variable sources that are suitable for future coordinated multi-wavelength studies. The photometric variability that we are seeking is related to accretion and/or outflow activity. The target list is selected from Spitzer observations of star forming regions in Cepheus, Perseus, Taurus and Orion, and includes targets contained in the Spitzer FEPS, c2d and Taurus Legacy Projects. These programs have identified a large selection of WTTSs and CTTSs with varying disk morphologies and ages of order 10^6 years. Optical photometry exists for most of these sources, however their variability is for the most part unknown.
