| Abstract: | Using 22 $\mu$m data from the Wide Field Infrared Survey Explorer (WISE), we have completed a sensitive all-sky survey for Hipparcos and Tycho catalog stars within 120 pc with debris disks. This warm excess emission traces material in the circumstellar region likely to host terrestrial planets. Several hundred previously unknown debris disk candidates were identified. We are currently performing follow-up observations to characterize the stars, companions, and circumstellar material in these systems. About 120 WISE debris disk candidate stars were observed with Herschel/PACS at 70 and 160 microns. While the bulk of these sources were recovered by Herschel, about 20% appear to have offsets between the stellar position and the source of long wavelength emission, indicating contamination by star-galaxy superpositions. The rest suggest a mixture of cold and multi-zone debris belts among stars in the sample. Thirteen WISE debris disks have been observed to date using HST/STIS coronagraphy. Five of these disks have been detected in scattered light. One is a large and highly asymmetric edge-on disk which appears to be both warped and bifurcated. We have an ongoing program of Keck coronography to search for faint common proper motion substellar companions, with several promising candidates awaiting confirmation. |
