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 to their possible existence can nevertheless be obtained from observations of the circumstellar debris disks of dust from which they form. The presence of such disks has been inferred from excess far-infrared emission but, with the exception of β Pictoris, it has proved difficult to image these… 
Kuiper belts around nearby stars
Context. The existence of dusty debris disks around a large fraction of solar type main-sequence stars, inferred from excess far-IR and submillimetre emission compared to that expected from stellar

Dusty Planetary Systems
Extensive photometric stellar surveys show that many main sequence stars show emission at infrared and longer wavelengths that is in excess of the stellar photosphere; this emission is thought to
Deep Keck Adaptive Optics Searches for Extrasolar Planets in the Dust of Eridani and Vega
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
Submillimeter Observations of an Asymmetric Dust Disk around Fomalhaut
New submillimeter images of the cold dust emission around the nearby main-sequence star Fomalhaut are presented. Observations at a wavelength of 450 lm, where the telescope beam size is equivalent to
We use mid-infrared Spitzer spectroscopy and far-infrared Herschel photometry for a sample of 20 main sequence O9-B2 stars in the Small Magellanic Cloud (SMC) with strong 24 μm excesses to
Herschel observations of debris discs orbiting planet-hosting subgiants
Debris discs are commonly detected orbiting main-sequence stars, yet little is known regarding their fate as the star evolves to become a giant. Recent observations of radial velocity detected
A submillimetre search for cold extended debris disks in the β Pictoris moving group
Context: Previous observations with the Infrared Astronomical Satellite and the Infrared Space Observatory, and ongoing observations with Spitzer and AKARI, have led to the discovery of over 200
A search for debris discs around stars with giant planets
Eight nearby stars with known giant planets have been searched for thermal emission in the submillimetre arising from dust debris. The null results imply quantities of dust typically less than 0.02
On the Flux of Extrasolar Dust in Earth’s Atmosphere
Micron-size extrasolar dust particles have been convincingly detected by satellites. Larger extrasolar meteoroids (5-35 μm) have most likely been detected by ground-based radar at Arecibo and New


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
A Circumstellar Disk Around β Pictoris
A circumstellar disk has been observed optically around the fourth-magnitude star β Pictoris. First detected in the infrared by the Infrared Astronomy Satellite last year, the disk is seen to extend
Far-Infrared Constraints on Dust Shells Around Vega-like Stars
We present results of observations at 47 and 95 microns from the Kuiper Airborne Observatory of several ``Vega-like'' stars. Spatial cuts and aperture photometry are presented for Beta Pictoris,
Dust disks around Vega-type stars
1300 μm observations of the circumstellar dust around Vega-type stars are presented. A comparison of the new data (24″ HPBW) for α PsA, τ 1 Eri with previous measurements made at an angular
Radiation-induced Warping of Protostellar Accretion Disks
We examine the consequences of radiatively driven warping of accretion disks surrounding pre-main-sequence stars. These disks are stable against warping if the luminosity arises from a steady
A Protocometary Cloud around HR 4796A
We report both ROSAT observations and ground-based 10.8 ?m imaging of the wide binary HR 4796, which consists of a main-sequence A-type star with a large amount of circumstellar dust, HR 4796A, and,
Model of a Kuiper Belt Small Grain Population and Resulting Far-Infrared Emission
We have calculated a simple model of the expected Kuiper Belt (KB) small grain population and the thermal emission that would arise from such grains. We have also sought observational evidence for
A Deep Submillimeter Survey of Lensing Clusters: A New Window on Galaxy Formation and Evolution
We present the first results of a submillimeter survey of distant clusters using the new Submillimeter Common-User Bolometer Array (SCUBA) on the James Clerk Maxwell Telescope. We have mapped fields
Vega: smaller grains in a larger shell
We have re-analysed the IRAS pointed observations of Vega. We find that the 60 μm emission of Vega is as extended as 35±5 arcsec. This is much larger than the generally accepted 23 arcsec (Aumann et
A Jupiter-mass companion to a solar-type star
The presence of a Jupiter-mass companion to the star 51 Pegasi is inferred from observations of periodic variations in the star's radial velocity. The companion lies only about eight million
