Combined Light Curves and Variable High Resolution Imaging of Taurus YSOs
Abstract
Young Stellar Objects (YSOs) were first identified as a distinct class based on their intrinsic variability. For Class I-Class II YSOs, the suggested underlying physical mechanisms fall primarily into two categories: (i) magnetic disk accretion onto the photosphere, resulting in a hot spot; or (ii) shadowing by an induced warp in the accretion disk. We present new light curves for seven Taurus YSOs obtained with the NOAO WIYN telescope infrared camera WHIRC over 14 nights in December 2014. All of the observed objects also have at least two epochs of high resolution HST NICMOS infrared images in which variations have been observed. By combining these two different data sets with radiation transfer models of the objects, we will investigate the physical processes of variability for a group of objects where the geometrical effects are well constrained.
