Mid-IR Observations of Mira Circumstellar Environment
Massimo Marengo, Margarita Karovska, Giovanni G. Fazio +4
This paper presents results from high-angular resolution mid-IR imaging of the Mira AB circumbinary environment using the MIRAC3 camera at the NASA Infrared Telescope Facility (IRT…
Subarcsecond Mid-IR Structure of the Dust Shell around IRAS 22272+5435
T. Ueta, M. Meixner, P. M. Hinz +6
We report sub-arcsecond imaging of extended mid-infrared emission from a proto-planetary nebula (PPN), \iras 22272+5435, performed at the MMT observatory with its newly upgraded 6.…
Spatial Distributions of Multiple Dust Components in the PPN/PN Dust Shells
Toshiya Ueta, Angela K. Speck, Margaret Meixner +5
We investigate spatial distributions of specific dust components in the circumstellar shells of a proto-planetary nebula candidate, HD 179821, and a planetary nebula, BD$+30^{\circ…
Discovery of an Extended Dust Emission around IRAS 18576+0341 (AFGL 2298) at 10.3 and 18.0 microns: a New Luminous Blue Variable Candidate?
Toshiya Ueta, Margaret Meixner, Aditya Dayal +4
We report detection of an extended mid-infrared emission from \iras 18576+0341 (AFGL 2298). The object shows a dusty circumstellar shell that has diameter of $\age 7\arcsec$ at 10.…
Mid-infrared imaging of the massive young star AFGL 2591: Probing the circumstellar environment of an outflow source
Massimo Marengo, Ray Jayawardhana, Giovanni G. Fazio +4
Most, if not all, stars are now believed to produce energetic outflows during their formation. Yet, almost 20 years after the discovery of bipolar outflows from young stars, the or…
Wide-Field Thermal Imaging of the Orion Nebula at High Spatial Resolution
L. K. Deutsch, M. Kassis, N. Smith +5
We describe multi-wavelength (8--20 micron), diffraction-limited, mid-infrared images of the OMC-1 cloud core in Orion, covering an approximately two arcminute area around the Trap…
Revealing the Photodissociation Region: Hubble Space Telescope/NICMOS Imaging of NGC 7027
William B. Latter, Aditya Dayal, John H. Bieging +4
We report results from a Hubble Space Telescope (HST) and Near-Infrared Camera and Multiobject Spectrometer (NICMOS) program to study the distribution of hot neutral (molecular hyd…
HST/NICMOS Imaging of the Planetary Nebula Hubble 12
Joseph L. Hora, William B. Latter, Aditya Dayal +4
Images of Hubble 12 were obtained with the HST/NICMOS instrument in the F110W, F164N, and F166N filters of NIC1, and the F160W, F187N, F190N, F212N, F215N filters of NIC2. The imag…
A Mid-Infrared Imaging Survey of Proto-Planetary Nebula Candidates
Margaret Meixner, Toshiya Ueta, Aditya Dayal +6
We present the data from a mid-infrared imaging survey of 66 proto-planetary nebula candidates using two mid-IR cameras (MIRAC2 and Berkcam) at the NASA Infrared Telescope Facility…
