Spatial variation in temperature and density in the IC 63 PDR from Spectroscopy
Archana Soam, B-G Andersson, Janik Karoly +2
We have measured the gas temperature in the IC 63 photodissociation region (PDR) using the S(1) and S(5) pure rotation lines of molecular hydrogen with SOFIA/EXES. We divide the PD…
High-Resolution Mid-Infrared Spectroscopy of GV Tau N: Surface Accretion and Detection of Ammonia in a Young Protoplanetary Disk
Joan R. Najita, John S. Carr, Sean D. Brittain +3
Physical processes that redistribute or remove angular momentum from protoplanetary disks can drive mass accretion onto the star and affect the outcome of planet formation. Despite…
High Resolution Infrared Spectroscopy of Hot Molecular Gas in AFGL 2591 and AFGL 2136: Accretion in the Inner Regions of Disks Around Massive Young Stellar Objects
Andrew G. Barr, Adwin Boogert, Curtis N. DeWitt +8
We have performed a high resolution 4-13 spectral survey of the hot molecular gas associated with the massive protostars AFGL 2591 and AFGL 2136, utilising the Echelon-Cross-E…
The HO Spectrum of the Massive Protostar AFGL 2136 IRS 1 from 2 to 13 m at High Resolution: Probing the Circumstellar Disk
Nick Indriolo, D. A. Neufeld, A. G. Barr +6
We have observed the massive protostar AFGL 2136 IRS 1 in multiple wavelength windows in the near-to-mid-infrared at high ( km s) spectral resolution using VLT+CRIRES…
SOFIA-EXES Observations of Betelgeuse during the Great Dimming of 2019/2020
Graham M. Harper, Curtis N. DeWitt, Matthew J. Richter +6
In 2019 October Betelgeuse began a decline in V-band brightness that went beyond the minimum expected from its quasi-periodic ~420 day cycle, becoming the faintest in recorded phot…
Supernova Shocks in Molecular Clouds: Velocity Distribution of Molecular Hydrogen
William T. Reach, Le Ngoc Tram, Matthew Richter +2
Supernovae from core-collapse of massive stars drive shocks into the molecular clouds from which the stars formed. Such shocks affect future star formation from the molecular cloud…
