We have simulated the irradiation of circumstellar disk atmospheres around pre-main sequence stars and generated emission line spectra using the photoionization code Cloudy. For the nearby T Tauri star TW Hya, we have predicted some of the physical conditions in this star+disk system by matching model emission lines to the observed spectral line of [Ne II]. We have determined that both X-ray and UV radiation contribute to the observed line luminosity of [Ne II]. We have also constrained the range of star-disk separations and the disk densities that give rise to the observed spectral line. By placing constraints on the physical properties of such systems, we can learn more about the conditions that allow or hinder planet formation and disk dissipation.
