Title: A NEWFIRM JHK variability study of 4-10 Myr members of the Orion OB1 association

Abstract: We propose to carry out a coordinated optical/near-IR photometric monitoring program, to study the multi-wavelength variability of 4-10 Myr stars, with the goal of investigating temporal phenomena linked to the inner structure of circumstellar disks, and to the physics and early evolution of (circum)stellar activity. Our target fields are located in the Orion OB1 association, for which we already have an extensive set of ancillary data. Our program will allow us to explore variability from the optical to the IR, on timescales ranging from hours to a few months, at this yet uncharted age range when disks have evolved and planets are expected to have formed.
