Detection of the S(1) Rotational Line of H2 toward IRC+10216: A Simultaneous Measurement of Mass-Loss Rate and CO Abundance
J. P. Fonfría, C. N. DeWitt, E. J. Montiel +2
We report the first detection of the S(1) pure rotational line of ortho-H2 at 17.04 um in an asymptotic giant branch star, using observations of IRC+10216 with the Echelon-cross-ec…
Multi-frequency high spectral resolution observations of HCN toward the circumstellar envelope of Y CVn
J. P. Fonfría, E. J. Montiel, J. Cernicharo +7
High spectral resolution observations toward the low mass-loss rate C-rich, J-type AGB star Y CVn have been carried out at 7.5, 13.1 and 14.0 um with SOFIA/EXES and IRTF/TEXES. Aro…
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…
Disentangling Dust Components in SN 2010jl: The First 1400 Days
A. M. Bevan, K. Krafton, R. Wesson +6
The luminous Type IIn SN 2010jl shows strong signs of interaction between the SN ejecta and dense circumstellar material. Dust may be present in the unshocked ejecta, the cool, den…
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…
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…
