Detection of propadiene (CH $_{2}$ CCH $_{2}$ ), propene (C $_{3}$ H $_{6}$ ) and non-detection of propane (C $_{3}$ H $_{8}$ ) in Jupiter's northern polar stratosphere

James A. Sinclair, Thomas K. Greathouse, Rohini S. Giles +8

We report the first detection of stratospheric propadiene (CH $_{2}$ CCH $_{2}$ ) and propene (C $_{3}$ H $_{6}$ ) at Jupiter's mid-to-high northern latitudes using IRTF-TEXES measurements recorde…

High-resolution mid-IR spectroscopy of SVS 13-A with EXES/SOFIA: The surprisingly high CH $_{3}$ OH/H $_{2}$ O ratio in the planet-forming zone of a solar mass protostar

Curtis DeWitt, Marta De Simone, Eleonora Bianchi +8

Water and methanol are key components of interstellar ices and gas in star- and planet-forming regions, but direct observations of water in low-mass protostars are challenging due…

The Discovery of 25 um Interstellar Methanol

Sarah L. Nickerson, Naseem Rangwala, Keeyoon Sung +15

We present the first astrophysical detection of methanol (CH3OH) in the torsional band near 25 um. Using high resolution mid-infrared (MIR) spectroscopy, we identified over seventy…
