High Resolution Mid - Infrared Imaging of the AGB Star RV Boo with the Steward Observatory Adaptive Optics System
B. A. Biller, L. M. Close, A. Li +9
We present high resolution (~0.1"), very high Strehl ratio (0.97+-0.03) mid-infrared (IR) adaptive optics (AO) images of the AGB star RV Boo utilizing the MMT adaptive secondary AO…
Adaptive Optics Nulling Interferometric Constraints on the Mid-Infrared Exozodiacal Dust Emission around Vega
W. M. Liu, P. M. Hinz, W. F. Hoffmann +7
We present the results of mid-infrared nulling interferometric observations of the main-sequence star alpha Lyr (Vega) using the 6.5 m MMT with its adaptive secondary mirror. From…
Mid-Infrared Imaging of the Post-AGB Star AC Herculis with the MMT Adaptive Optics System
Laird M. Close, Beth Biller, William F. Hoffmann +8
We utilized the MMT's unique deformable secondary adaptive optics system to produce high-resolution (FWHM=0.3"), very high Strehl mid-infrared (9.8, 11.7 & 18 micron) images of the…
High Resolution Images of Orbital Motion in the Trapezium Cluster: First Scientific Results from the MMT Deformable Secondary Mirror Adaptive Optics System
Laird M. Close, Francois Wildi, Michael Lloyd-Hart +16
We present the first scientific images obtained with a deformable secondary mirror adaptive optics system. We utilized the 6.5m MMT AO system to produce high-resolution (FWHM=0.07'…
