We present high spatial resolution mid- and far-infrared images of the Vega debris disk obtained with the Multiband Imaging Photometer for Spitzer (MIPS). The disk is well resolved, and its angular size is much larger than found previously. The radius of the disk is at least 43'' (330 AU), 70'' (543 AU), and 105'' (815 AU) in extent at 24, 70, and 160 μm, respectively. The disk images are circular, smooth, and without clumpiness at all three wavelengths. The radial surface brightness profiles… 
Resolved Imaging of the HR?8799 Debris Disk with Herschel
We present Herschel far-infrared and submillimeter maps of the debris disk associated with the HR 8799 planetary system. We resolve the outer disk emission at 70, 100, 160 and 250 µm and detect the
The Vega debris disc: A view from Herschel
We present five band imaging of the Vega debris disc obtained using the Herschel Space Observatory. These data span a wavelength range of 70-500 mu m with full-width half-maximum angular resolutions
The debris disk around gamma Doradus resolved with Herschel
We present observations of the debris disk around gamma Doradus, an F1V star, from the Herschel Key Programme DEBRIS (Disc Emission via Bias-free Reconnaissance in the Infrared/Submillimetre). The
Circumstellar material in the Vega inner system revealed by CHARA/FLUOR
Context. Only a handful of debris disks have been imaged up to now. Due to the need for high dynamic range and high angular resolution, very little is known about the inner planetary region, where
Epsilon Eridani's planetary debris disk: structure and dynamics based on Spitzer and Caltech submillimeter observatory observations
Spitzer and Caltech Submillimeter Observatory images and spectrophotometry of Eridani at wavelengths from 3.5 to 350 μm reveal new details of its bright debris disk. The 350 μm map confirms the
Mid-Infrared Resolution of a 3 AU Radius Debris Disk around ζ Leporis*
We present subarcsecond-resolution mid-infrared images of the debris disk surrounding the 230 Myr old A star ζ Lep. Our data obtained with T-ReCS at Gemini South show the source to be unresolved at
Mid-Infrared Imaging of Two Circumstellar Disks: the cases ofHD 179218 and Epsilon Eridani.
Recently, large ground-based telescopes and the new generation of astronomical instrumentation have allowed us to examine the environments of young stellar objects with high angular resolution.
The HIP 79977 debris disk in polarized light
We present observations of the known edge-on debris disk around HIP 79977 (HD 146897, F star in Upper Sco, 123 pc), taken with the ZIMPOL differential polarimeter of the SPHERE instrument in the Very
Confirming the Primarily Smooth Structure of the Vega Debris Disk at Millimeter Wavelengths
Clumpy structure in the debris disk around Vega has been previously reported at millimeter wavelengths and attributed to concentrations of dust grains trapped in resonances with an unseen planet.
Resolving Structure in the Debris Disk around HD 206893 with ALMA
Debris disks are tenuous, dusty belts surrounding main-sequence stars generated by collisions between planetesimals. HD 206893 is one of only two stars known to host a directly imaged brown dwarf


First look at the Fomalhaut debris disk with the Spitzer Space Telescope
We present Spitzer Space Telescope early release observations of Fomalhaut, a nearby A-type star with dusty circumstellar debris. The disk is spatially resolved at 24, 70, and 160 � m using the
Infrared Views of the TW Hydra Disk
The face-on disk around TW Hya is imaged in scattered light at 1.1 and 1.6 km using the coronagraph in the Near Infrared Camera and Multi Object Spectrometer aboard the Hubble Space Telescope.
Hubble Space Telescope ACS Coronagraphic Imaging of the Circumstellar Disk around HD 141569A
Multicolor coronagraphic images of the circumstellar disk around HD 141569A have been obtained with the Hubble Space Telescope Advanced Camera for Surveys. The B, V, and I images show that the disk's
Infrared mapping of the dust disc around Vega
ISOPHOT has been used to perform high-resolution 60-μm scans of Vega, and these have been compared with those from γDra, to obtain a Gaussian width of 22±2 arcsec. The dust disc around Vega has been
A Dust Ring around epsilon Eridani: Analog to the Young Solar System
Dust emission around the nearby star Eridani has been imaged using a new submillimeter camera (the Submillimetre Common-User Bolometer Array at the James Clerk Maxwell Telescope). At an 850 μm
Infrared Observations Of Dust Emission From Comet Hale-Bopp
We present infrared imaging and photometry of the bright, giant comet C/1995 O1 (Hale-Bopp). The comet was observed in an extended infrared and optical observing campaign in 1996–1997. The infrared

We present images of the Vega system obtained with the IRAM Plateau de Bure interferometer at a 1.3 mm wavelength with submillijansky sensitivity and ~25 resolution (about 20 AU). These observations
Millimeter-Wave Aperture Synthesis Imaging of Vega: Evidence for a Ring Arc at 95 AU
We present the first millimeter-wave aperture synthesis map of dust around a main-sequence star. A 3'' resolution image of 1.3 mm continuum emission from Vega reveals a clump of emission 12'' from
On the far-infrared excess of Vega
The Infrared Astronomy Satellite (IRAS) has recently detected a compact far-infrared emission source associated with Vega (α Lyrae)1. This flux appears to be thermal emission from dust heated by the
Submillimeter studies of main-sequence stars
JCMT maps of the 800-micron emission from Vega, Fomalhaut, and Beta Pictoris are interpreted to indicate that they are not ringed by large reservoirs of distant orbiting dust particles that are too
