Spatially Resolving the Disk Mass Accretion Process In Young Star Binaries
Abstract
We request HST ACS SBC images in the F140LP and F165LP filters in order to spatially resolve UV emission from H2 gas and scattered light emerging from structures in the planet-forming environments of two young binary systems: GG Tau A and UY Aur. These data, in conjunction with a suite of high-angular resolution ground-based observations -- including spectral images of near-IR H2 emission, mm observations of dust continuum and CO gas emission through allocated ALMA "Cycle 0" observations -- will allow us to characterize the morphology of gas and dust passing between the circumbinary and circumstellar disks. Multi-wavelngth mapping of the distribution of material in GG Tau and UY Aur will reveal the role tidal truncation plays in the formation of planets in binary systems and help to constrain a growing number of hydrodynamic simulations of the complex disk-disk interactions.
