High-resolution mid-IR spectroscopy of SVS 13-A with EXES/SOFIA: The surprisingly high CHOH/HO 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…
A Tale of Two Sightlines: Comparison of Hydrocarbon Dust Absorption Bands toward Cygnus OB2-12 and the Galactic Center
Yvonne J. Pendleton, T. R. Geballe, Laurie E. U. Chu +14
Infrared spectra of hydrocarbon dust absorption bands toward the bright hypergiant Cygnus OB2-12 are compared to published spectra of the Quintuplet Cluster, a sightline to the Gal…
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…
Supernova Shocks in Molecular Clouds: Shocks Driven into Dense Cores in IC 443 and 3C 391
William T. Reach, Ngoc Le Tram, Curtis DeWitt +3
Supernova shocks into dense molecular cores in IC 443 (clumps B, C, and G) and 3C 391 were observed using the Stratospheric Observatory for Infrared Astronomy and complemented by a…
SOFIA/EXES observations of warm H2 at high spectral resolution: II. IC443C, NGC2071, and 3C391
David A. Neufeld, Curtis DeWitt, Pierre Lesaffre +4
Using the EXES instrument on SOFIA, we have obtained velocity-resolved spectra of several pure rotational lines of H2 toward shocked molecular gas within three Galactic sources: th…
Unveiling two deeply embedded young protostars in the S68N Class 0 protostellar core with JWST/NIRSpec
Valentin J. M. Le Gouellec, Ben W. P. Lew, Thomas P. Greene +11
The near-infrared (NIR) emission of the youngest protostars still needs to be characterized to better understand the evolution of their accretion and ejection activity. We analyze…
