SOFIA/FORCAST Observations of the Luminous Blue Variable Candidates MN 90 and HD 168625
Ryan Arneson, Dinesh Shenoy, Nathan Smith +1
We present SOFIA/FORCAST imaging of the circumstellar dust shells surrounding the luminous blue variable (LBV) candidates MN 90 and HD 168625 to quantify the mineral abundances of…
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…
Rise and fall of the dust shell of the classical nova V339 Delphini
A. Evans, D. P. K. Banerjee, R. D. Gehrz +16
We present infrared spectroscopy of the classical nova V339 Delphini, obtained over a year period. The infrared emission lines were initially symmetrical, with HWHM velocit…
Searching for Cool Dust in the Mid-to-Far Infrared: the Mass Loss Histories of The Hypergiants Cep, VY CMa, IRC+10420, and Cas
Dinesh Shenoy, Roberta M. Humphreys, Terry Jay Jones +6
We present mid- and far- IR imaging of four famous hypergiant stars: the red supergiants Cep and VY CMa, and the warm hypergiants IRC +10420 and Cas. Our 11 to 37 m SOFI…
Panchromatic imaging and spectroscopic observations of the mass ejections of RY Scuti
Robert D. Gehrz, Nathan Smith, Dinesh Shenoy
We describe recent panchromatic imaging and spectroscopic studies of the supergiant, mass-transferring, binary star RY Scuti, which is in a brief transitional phase to become a Wol…
Probing Hypergiant Mass Loss with Adaptive Optics Imaging & Polarimetry in the Infrared: MMT-Pol and LMIRCam observations of IRC +10420 & VY Canis Majoris
Dinesh P. Shenoy, Terry J. Jones, Chris Packham +1
We present 2 - 5 micron adaptive optics (AO) imaging and polarimetry of the famous hypergiant stars IRC +10420 and VY Canis Majoris. The imaging polarimetry of IRC +10420 with MMT-…
Observations of Type Ia Supernova 2014J with FLITECAM/SOFIA
William D. Vacca, Ryan T. Hamilton, Maureen Savage +9
We present medium resolution near-infrared (NIR) spectra, covering 1.1 to 3.4 microns, of the normal Type Ia supernova (SN Ia) SN 2014J in M82 obtained with the FLITECAM instrument…
Adaptive Optics Imaging of VY Canis Majoris at 2 - 5 micron with LBT/LMIRCam
Dinesh P. Shenoy, Terry J. Jones, Roberta M. Humphreys +11
We present adaptive optics images of the extreme red supergiant VY Canis Majoris in the Ks, L' and M bands (2.15 to 4.8 micron) made with LMIRCam on the Large Binocular Telescope (…
Elemental Abundances in the Ejecta of Old Classical Novae from Late-Epoch Spitzer Spectra
