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…
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…
Constraining the Lifetime of Circumstellar Disks in the Terrestrial Planet Zone: A Mid-IR Survey of the 30-Myr-old Tucana-Horologium Association
Eric E. Mamajek, Michael R. Meyer, Philip M. Hinz +3
We have conducted an N-band survey of 14 young stars in the ~30 Myr-old Tucana-Horologium Association to search for evidence of warm, circumstellar dust disks. Using the MIRAC-BLIN…
