β Pictoris (β Pic) is a main-sequence star with an edge-on dust disk that might represent a state of the early Solar System. The dust does not seem to be a remnant from the original protoplanetary disk, but rather is thought to have been generated from large bodies like planetesimals and/or comets. The history and composition of the parent bodies can therefore be revealed by determining the spatial distribution, grain size, composition and crystallinity of the dust through high-resolution mid… Expand

Mid-infrared images of β Pictoris and the possible role of planetesimal collisions in the central disk
Thermal infrared images of the central disk imply that the brightness asymmetry results from the presence of a bright clump composed of particles that may differ in size from dust elsewhere in the disk, which is suggested to result from the collisional grinding of resonantly trapped planetesimals or the cataclysmic break-up of a planetesimal.

Comet-like mineralogy of olivine crystals in an extrasolar proto-Kuiper belt
The detection of the 69-micrometre-wavelength band of olivine crystals in the spectrum of β Pictoris shows values strikingly similar to those for the dust emitted by the most primitive comets in the Solar System, even though β’Pictoris is more massive and more luminous and has a different planetary system architecture.

Evidence for an additional planet in the β Pictoris system
With its imaged debris disk of dust, its evaporating exocomets, and an imaged giant planet, the young (~23 Myr) β Pictoris system is a unique proxy for detailed studies of planet formation processesExpand

Two families of exocomets in the β Pictoris system
An analysis of more than 1,000 archival spectra gathered between 2003 and 2011 provides a sample of about 6,000 variable absorption signatures arising from exocomets transiting the disk of the parent star, showing that the evaporating bodies observed for decades in the β Pictoris system are analogous to the comets in the Solar System.

A probable giant planet imaged in the beta Pictoris disk. VLT/NaCo deep L'-band imaging
Context: Since the discovery of its dusty disk in 1984, β Pictoris has become the prototype of young early-type planetary systems, and there are now various indications that a massive Jovian planetExpand
