Scientific paper

We propose to conduct a multi-wavelength monitoring campaign of two classical T Tauri stars (TW Hya and GM Aur) that possess transitional disks, produce variable [Ne II] emission, generate substantial X-ray emission, and are still actively accreting. Leveraging the variable nature of X-rays, [Ne II] emission, and the mass accretion rates of these sources, we will search for a correlations in these data to provide the first direct observational evidence of the role X-rays and EUV photons play in driving disk chemistry and the evolution of proto-planetary disks. We request three independent observations of each source over the next year supported by ground-based observations with the mid-IR spectrograph MICHELLE on Gemini North and the R-C optical spectrograph on SMARTS at CTIO.
