Water and Organic Volatiles in Protoplanetary Disks: The Case of GV Tau N

How water and volatiles are distributed through proto- planetary disks around young stars is of astrobiological interest, particularly as it relates to the question of how terrestrial planets in our solar system acquired water and organics. We present high-resolution (λ/Δλ~25,000), near-infrared spectroscopic L-band observations toward T Tauri star GV Tau N. The data were acquired in 2010 with the NIRSPEC instrument on Keck II, located on Mauna Kea, HI as part of a spectral survey. We detected strong absorption due to several molecules, including several bands of water, HCN, and C2H2 that we interpret to be lo- cated in the warm molecular layer of the nearly edge-on protoplanetary disk.
