Title: Variability of Edge-On YSOs in Taurus
Abstract: One of the prominent features of Young Stellar Objects (YSOs) is photometric and spectroscopic variability. Recent studies have indicated that this variability may be linked to accretion hot spots, magnetic instabilities, disk warps, or density enhancements in the inner disk. Most investigations rely on fitting aperture photometry to the light curves of multiple objects to explore the underlying mechanisms of variability. In the Taurus-Auriga star forming region, however, there are a handful of disk sources whose line-of-sight orientation creates an additional means of investigation. In very high-resolution images of the light scattered off their disks, their detailed morphology is also variable. These sources provide a unique opportunity to investigate variability by combining state of the art radiation transfer models with synoptic high-resolution imaging, photometry and spectroscopy. We propose to obtain light curves for these objects to place them into the context of current photometric work and enable us to design an efficient multiple platform observational program.
