Title: Disk Wall Variability in Pre-Main Sequence Disks

Abstract: We have detected changes in the SEDs, interference fringes, and scattered light images of pre-main sequence disk systems. These changes, occurring on time scales of months to years, signal dynamical changes in the structure of the inner disks in these systems. Coordinated observations with multiple facilities probe different aspects of the disk structure & dynamics, and their combined data sets are far more powerful than those obtained in isolation. We will obtain BVRIJHK photometric data that will stand on its own and will also support a joint IRTF program to study these systems.
