Title: Investigating Hot Water in YSO Disks using Cross Dispersed IR Spectroscopy

Abstract: To significantly improve our understanding of water in terrestrial planet forming environments, we have initiated a program to characterize the poorly understood broad hot water emission features in the 1.0 to 2.5 um spectra of young stars. Our aim is to use infrared spectroscopy and young star spectral characteristics that probe the YSO accretion, outflow and wind phenomena to 1) determine the true prevalence of this hot water vapor emission in young stellar objects (YSOs), 2) estimate the physical properties of the detected water vapor to constrain its location in the YSO environments, and 3) determine correlations between hot water emission and stellar accretion and outflow properties. In this proposal, we request 3 nights of observing time with SOAR using the OSIRIS cross dispersed spectrograph to measure water emission from YSOs in southern star forming regions, observable in the May-June time frame in Chile.
