The infrared view of dust and molecules around V4334 Sgr (Sakurai's Object): a 20-year retrospective
A. Evans, R. D. Gehrz, C. E. Woodward +16
We present an analysis of the evolution of circumstellar dust and molecules in the environment of the very late thermal pulse object V4334 Sgr (Sakurai's Object) over a -ye…
Gas phase SiO in the circumstellar environment of the recurrent nova T Coronae Borealis
A. Evans, Ya. V. Pavlenko, D. P. K. Banerjee +9
We report the discovery of the diatomic molecule SiO in the gas phase in the environment of the recurrent nova T Coronae Borealis. While some of the SiO is photospheric, a substant…
The Unexpected Spectrum of the Innermost Ejecta of the Red Hypergiant VY CMa
Roberta M. Humphreys, L. M. Ziurys, J. J. Bernal +6
HST/STIS spectra of the small clumps and filaments closest to the central star in VY CMa reveal that the very strong K I emission and TiO and VO molecular emission, long thought to…
The Temporal Development of Dust Formation and Destruction in Nova Sagittarii 2015#2 (V5668 Sgr): A Panchromatic Study
R. D. Gehrz, A. Evans, C. E. Woodward +15
We present 5-28 micron SOFIA FORECAST spectroscopy complemented by panchromatic X-ray through infrared observations of the CO nova V5668 Sgr documenting the formation and destructi…
Searching for Cool Dust: II. Infrared Imaging of the OH/IR Supergiants, NML Cyg, VX Sgr, S Per and the Normal Red Supergiants RS Per and T Per
Michael S. Gordon, Roberta M. Humphreys, Terry J. Jones +6
New MMT/MIRAC (9-11 μm), SOFIA/FORCAST (11-37 μm), and Herschel/PACS (70 and 160 μm) infrared (IR) imaging and photometry is presented for three famous OH/IR red supergiants (NML C…
A SOFIA FORCAST Grism Study of the Mineralogy of Dust in the Winds of Proto-planetary Nebulae: RV Tauri Stars and SRd Variables
R. A. Arneson, R. D. Gehrz, C. E. Woodward +10
We present a SOFIA FORCAST grism spectroscopic survey to examine the mineralogy of the circumstellar dust in a sample of post-asymptotic giant branch yellow supergiants that are be…
