Title: Locating the water vapor in protoplanetary disks

Abstract: Studying water vapor in protoplanetary disks can provide crucial insights into the processes that lead to diverse planetary systems. In this study, we aim to understand the cause of a large range of water vapor line strengths observed with the Spitzer-IRS in a sample of protoplanetary disks. By resolving these emission lines using TEXES on Gemini, we will investigate whether the spatial origin of the emission plays a role in determining emission line strengths. In particular, we will look for differences in spatial extent, perhaps due to differing condensation front locations, and search for any evidence of disk winds. If we understand the origin of differences in line fluxes, we can then apply this understanding to interpret the water vapor emission in our much larger sample of disks observed with the Spitzer-IRS.
