Photometry using the Infrared Array Camera on the Spitzer Space Telescope
Joseph L. Hora, Sean Carey, Jason Surace +13
We present several corrections for point source photometry to be applied to data from the Infrared Array Camera (IRAC) on the Spitzer Space Telescope. These corrections are necessa…
Evidence for Misaligned Disks in the T Tauri Triple System: 10 um Super-Resolution with MMTAO and Markov Chains
Andrew Skemer, Laird Close, Philip Hinz +3
Although T Tauri is one of the most studied young objects in astronomy, the nature of its circumstellar environment remains elusive due, in part, to the small angular separation of…
Observations of Herbig Ae Disks with Nulling Interferometry
W. M. Liu, P. M. Hinz, M. R. Meyer +5
We present the results of 10 micron nulling interferometric observations of 13 Herbig Ae stars using the Magellan I (Baade) and the MMT 6.5 m telescopes. A portion of the observati…
Resolving the Dusty Circumstellar Structure of the Enigmatic Symbiotic Star CH Cygni with the MMT Adaptive Optics System
Beth A. Biller, Laird M. Close, Aigen Li +6
We imaged the symbiotic star CH Cyg and two PSF calibration stars using the unique 6.5m MMT deformable secondary adaptive optics system. Our high-resolution (FWHM=0.3"), very high…
Resolved Mid-Infrared Emission Around AB Aur and V892 Tau with Adaptive Optics Nulling Interferometric Observations
W. M. Liu, P. M. Hinz, W. F. Hoffmann +3
We present the results of adaptive optics nulling interferometric observations of two Herbig Ae stars, AB Aur and V892 Tau. Our observations at 10.3 microns show resolved circumste…
In-flight performance and calibration of the Infrared Array Camera (IRAC) for the Spitzer Space Telescope
J. L. Hora, the IRAC team
The Infrared Array Camera (IRAC) is one of three focal plane instruments on board the Spitzer Space Telescope. IRAC is a four-channel camera that obtains simultaneous broad-band im…
