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…
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…
The nitrogen carrier in protoplanetary disks
Klaus M. Pontoppidan, Colette Salyk, Andrea Banzatti +4
The dominant reservoirs of elemental nitrogen in protoplanetary disks have not yet been observationally identified. Likely candidates are HCN, NH and N. The relative abunda…
A high resolution mid-infrared survey of water emission from protoplanetary disks
Colette Salyk, John Lacy, Matt Richter +5
We present the largest survey of spectrally resolved mid-infrared water emission to date, with spectra for 11 disks obtained with the Michelle and TEXES spectrographs on Gemini Nor…
High-Resolution SOFIA/EXES Spectroscopy of Gas in the Massive Young Stellar Object MonR2 IRS3: Implications for the Sulfur Budget
Ryan Dungee, Adwin Boogert, Curtis N. DeWitt +10
Sulfur has been observed to be severely depleted in dense clouds leading to uncertainty in the molecules that contain it and the chemistry behind their evolution. Here, we aim to s…
