The young planetary system surrounding the star β Pictoris harbours active minor bodies. These asteroids and comets produce a large amount of dust and gas through collisions and evaporation, as happened early in the history of our Solar System. Spectroscopic observations of β Pictoris reveal a high rate of transits of small evaporating bodies, that is, exocomets. Here we report an analysis of more than 1,000 archival spectra gathered between 2003 and 2011, which provides a sample of about 6,000…

An analysis of hundreds of star-grazing comets in a young planetary system shows that they form two families: a group of old, dried-out comets and a younger group probably related to the break-up of

It is reported that the sub-micrometre amorphous silicate grains around β Pic have peaks in their distribution around 6, 16 and 30’au (1 au is the Sun–Earth distance), whereas the crystalline and micrometr-sized amorphously silicategrain grains are concentrated in the disk centre.

Transient redshifted events monitored in the spectrum offl Pictoris have been interpreted for many years as resulting from the evaporation of numerous comet-like bodies in the vicinity of this stars.

Molecular hydrogen (H2) is by far the most abundant material from which stars, protoplanetary disks and giant planets form, but it is difficult to detect directly. Infrared emission lines from H2

The edge-on disk surrounding the nearby young star β Pictoris is the archetype of ‘debris disks’, which are composed of dust and gas produced by collisions between—and evaporation of—planetesimals,

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.

• Geology, Physics
Nature
• 2005
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.
