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 to more than 400 astronomical units from the star, or more than twice the distance measured in the infrared by the Infrared Astronomy Satellite. The β Pictoris disk is presented to Earth almost edgeon and is composed of solid particles in nearly coplanar orbits. The observed change in surface… Expand
Resolution of the circumstellar disk of β Pictoris at 10 and 20 µm
The A5 dwarf β Pic is a star that may be surrounded by a proto-planetary disk. Among the stars discovered with the Infrared Astronomical Satellite (IRAS) to have far-infrared excesses fromExpand
A rotating disk of gas and dust around a young counterpart to β Pictoris
β Pictoris is the best known example of a main-sequence star encircled by a tenuous disk. Optical, and infrared images of β Pic suggest that the disk is composed of dust grains which have beenExpand
β Pictoris, a young planetary system? A review
Abstract β Pictoris is a bright southern hemisphere star observed in 1983 by the IRAS satellite as presenting a large and unexpected IR excess. This excess was called the Vega-like phenomenon andExpand
Prospecting for planets in circumstellar dust: sifting the evidence from β Pictoris
Spectroscopic evidence for an extended gaseous shell around the A5V star β Pictoris has been available for more than a decade1–5. Recently, the presence of a vast circumstellar cloud of particles wasExpand
Circumstellar disks deduced from sub-arcsecond polarization observations of two young stars
HERBIG Ae/Be objects are young stars of intermediate mass (3–5 solar masses) surrounded by reflection nebulae composed of dust and gas remaining from the star-forming cloud1–3. Scattering by dustExpand
Widespread Atomic Gas Emission Reveals the Rotation of the β Pictoris Disk
We present high-resolution Na I D spectroscopy of the β Pictoris disk, and the resonantly scattered sodium emission can be traced from less than 30 AU to at least 140 AU from the central star. ThisExpand
CIRCUMSTELLAR DISKS AND OUTER PLANET FORMATION
The dust disk around β Pictoris must be produced by collision or by evaporation of orbiting Kuiper belt-like objects. Here we present the Orbiting- Evaporating-Bodies (OEB) scenario in which the diskExpand
BETA PICTORIS: An Early Solar System?
Beta Pictoris ( Pic) is the best studied of the normal main-sequence stars surrounded by circumstellar dust disks. We review the status of Pic and its disk, and compare it with both the early and theExpand
Fast-moving features in the debris disk around AU Microscopii
TLDR
High-contrast imaging reveals a series of five large-scale features in the southeast side of the debris disk that appear to move away from the star at projected speeds of 4–10 kilometres per second, suggesting highly eccentric or unbound trajectories if they are associated with physical entities.

Dust depletion in the inner disk of β Pictoris as a possible indicator of planets
IT is not yet possible to see planets orbiting other stars, although this may soon change as observing methods improve1. Indirect evidence for the presence of circumstellar dust disks out of whichExpand
