The HOSTS survey for exozodiacal dust: Observational results from the complete survey
Steve Ertel, Denis Defrère, Philip M. Hinz +43
The Large Binocular Telescope Interferometer (LBTI) enables nulling interferometric observations across the N band (8 to 13 um) to suppress a star's bright light and probe for fain…
Thermal Emission in the Southwest Clump of VY CMa
Michael S. Gordon, Terry J. Jones, Roberta M. Humphreys +6
We present high spatial resolution LBTI/NOMIC images of VY CMa and its massive outflow feature, the Southwest (SW) Clump. Combined with high-resolution imaging from HST…
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…
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…
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 (…
A Thermal Infrared Imaging Study of Very Low-Mass, Wide Separation Brown Dwarf Companions to Upper Scorpius Stars: Constraining Circumstellar Environments
Vanessa Bailey, Philip M. Hinz, Thayne Currie +18
We present a 3-5um LBT/MMT adaptive optics imaging study of three Upper Scorpius stars with brown dwarf (BD) companions with very low-masses/mass ratios (M_BD < 25M_Jup; M_BD / M_s…
