A Circumstellar Disk Around β Pictoris

  title={A Circumstellar Disk Around $\beta$ Pictoris},
  author={Bradford A. Smith and Richard Terrile},
  pages={1421 - 1424}
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… 

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 from

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 been

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 was

The far reaches of the β Pictoris debris disk

The nearby young star beta Pictoris hosts a rich and complex planetary system, with at least two giant planets and a nearly edge-on debris disk that contains several dynamical subpopulations of

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 dust

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. This

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 the


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 disk

A dust disk surrounding the young A star HR4796A

We report the codiscovery of the spatially resolved dust disk of the Vega-like star HR 4796A. Images of the thermal dust emission at λ=18 μm show an elongated structure approximately 200 AU in



On the nature of the material surrounding Vega

Observations of Vega at 193 microns indicate that the far-infrared emission from the circumstellar material discovered by IRAS (Aumann et al. 1984) may decline more rapidly than a Planck spectrum at


IRAS observations of Alpha Lyrae reveal a large infrared excess beyond 12 microns. The excess over an extrapolation of a 10,000 K blackbody is a factor of 1.3 at 25 microns, 7 at 60 microns, and 16

Close encounters between a star-planet system and a stellar intruder

This paper reports the results of nearly 40 000 computer simulations of close encounters between a planet-star (P-S) system and a stellar intruder. If the closest approach of the intruder is 2--3
