Title: The Carina Time-Series Deep Field

Abstract: We propose to conduct a time-series imaging campaign of the entire Carina region of massive star formation. Through a series of relatively short exposures we can identify essentially all the young stars in the region from their spot-induced variability. The program will also discover a long-sought-after collection of very young eclipsing pre-main- sequence binaries, thereby enabling direct stellar mass and radius measurements which are the only way to test theoretical evolutionary tracks of young stars quantitatively. The project will expand existing X-ray and IR-surveys by an order of magnitude, and will find tens of thousands of young stars of all masses in this rich region, including deep into the brown dwarf regime. Rotation periods for each object will show how stellar angular momenta depend upon masses and ages. By coadding all of the frames in each filter we will construct the first- ever `deep field' of a star-forming region. Carina, visible to the naked-eye and the premier massive star-forming region in the sky is the perfect target for such an endeavor. The resulting deep field will reveal a spectacular matrix of shells, outflows, and shock waves, but we cannot fully anticipate \it a-priori everything that might come from this effort. Finally, the results will guide development plans as to how LSST may be used to study galactic star formation.
