Using Near IR Spectroscopy For Characterization of Transiting Exoplanets
We propose a method for observing transiting exoplanets with near-infrared high-resolution spectrometers. We aim to create a robust data analysis method for recovering atmospheric transmission spectra from transiting exoplanets over […]

In-situ Measurements of the Radiation Stability of Amino Acids at 15-140 K
We present new kinetics data on the radiolytic destruction of amino acids measured in situ with infrared spectroscopy. Samples were irradiated at 15, 100, and 140 K with 0.8-MeV protons, […]

Glycine's Radiolytic Destruction in Ices: First In-Situ Laboratory Measurements for Mars
We report new laboratory studies of the radiation-induced destruction of glycine-containing ices for a range of temperatures and compositions that allow extrapolation to Martian conditions. In-situ infrared spectroscopy was used […]
