A significant population of nearby stars have strong far-infrared excesses, now known to be due to circumstellar dust in regions analogous to the Kuiper Belt of our solar system, although orders of magnitude more dense. Recent submillimeter and millimeter imaging of these systems resolves the circumstellar dust and reveals complex structures, often in the form of rings with azimuthal nonaxisymmetric variations. This structure might well be due to the presence of embedded brown dwarfs or planets…

High-contrast imaging with Spitzer: deep observations of Vega, Fomalhaut, and ϵ Eridani
Stars with debris disks are intriguing targets for direct imaging exoplanet searches, owing both to previous detections of wide planets in debris disk systems. and to commonly existing morphological
Fomalhaut and Eridani are two young, nearby stars that possess extended debris disks whose structures suggest the presence of perturbing planetary objects. With its high sensitivity and stable
Thermal infrared constraint to a planetary companion of vega with the MMT adaptive optics system
Vega may have a massive companion in a wide orbit, as evidenced by structure in its cold dust debris. We have tested this hypothesis by direct imaging with adaptive optics in the M band. The
High-contrast imaging search for planets and brown dwarfs around the most massive stars in the solar neighborhood
There has been a long-standing discussion in the literature as to whether core accretion or disk instability is the dominant mode of planet formation. Over the last decade, several lines of evidence
Limits on the optical brightness of the ∈ eridani dust ring
The STIS CCD camera on the Hubble Space Telescope (HST) was used to take deep optical images near the K2 V main-sequence starEridani in an attempt to find an optical counterpart of the dust ring
Deep imaging survey of the environment of Alpha Centauri - I. Adaptive optics imaging of Alpha Cen B with VLT-NACO
Context: Alpha Centauri is our closest stellar neighbor, at a distance of only 1.3 pc, and its two main components have spectral types comparable to the Sun. This is therefore a favorable target for
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
A Spitzer IRAC Search for Substellar Companions of the Debris Disk Star ∊ Eridani
We have used the Infrared Array Camera (IRAC) on board the Spitzer Space Telescope to search for low-mass companions of the nearby debris disk star Eri. The star was observed in two epochs 39 days
High-Contrast Imaging using Adaptive Optics for Extrasolar Planet Detection
Direct imaging of extrasolar planets is an important, but challenging, next step in planetary science. Most planets identified to date have been detected indirectly--not by emitted or reflected light
Imaging Extrasolar Giant Planets
High-contrast adaptive optics imaging is a powerful technique to probe the architectures of planetary systems from the outside-in and survey the atmospheres of self-luminous giant planets. Direct


Submillimetre images of dusty debris around nearby stars
Indirect detections of massive — presumably Jupiter-like — planets orbiting nearby Sun-like stars have recently been reported,. Rocky, Earth-like planets are much more difficult to detect, but clues
Observational confirmation of a circumsolar dust ring by the COBE satellite
ASTEROID collisions are an important source of the dust particles in the zodiacal cloud1–3. These particles spiral in towards the Sun under the influence of drag forces4–6 and, in passing through the

Signatures of the Giant Planets Imprinted on the Edgeworth-Kuiper Belt Dust Disk
One method to detect extrasolar planetary systems is to deduce the perturbations of planets on the observed circumstellar dust disks. Our solar system, with its known configuration of planets,
