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

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

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
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.
