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, analogues of Solar System comets and asteroids. These disks may provide insight into the formation and early evolution of terrestrial planets. Previous work on β Pic concluded that the disk gas has roughly solar abundances of elements, but this poses a problem because such gas should rapidly be blown… Expand

Herschel detects oxygen in the beta Pictoris debris disk
The young star β Pictoris is well known for its dusty debris disk produced through collisional grinding of planetesimals, kilometre-sized bodies in orbit around the star. In addition to dust, smallExpand
Molecular Gas Clumps from the Destruction of Icy Bodies in the β Pictoris Debris Disk
A highly asymmetric disk of dust and carbon monoxide orbiting the planet-hosting star, β Pictoris, delineates a region of enhanced collisions, either from a mean motion resonance with an unseen giant planet or from the remnants of a collision of Mars-mass planets. Expand
ON THE UNUSUAL GAS COMPOSITION IN THE β PICTORIS DEBRIS DISK
• Physics

Themetallic gas associated with the beta Pic debris disk is not believed to be primordial, but arises from the destruction of dust grains. Recent observations have shown that carbon and oxygen inExpand
Fe I in the β Pictoris circumstellar gas disk: II. Time variations in the circumstellar iron gas
Beta Pictoris is a young planetary system surrounded by a debris disk of dust and gas. The gas source of this disk could be exocomets (or 'falling and evaporating bodies', FEBs), which produceExpand
Herschel/HIFI observations of ionised carbon in the β Pictoris debris disk
Context. The dusty debris disk around the 20 Myr old main-sequence A-star Pictoris is known to contain gas. Evidence points towards a secondary origin of the gas as opposed to being a direct remnantExpand
Evolution of Debris Disks
Circumstellar dust exists around several hundred main sequence stars. For the youngest stars, that dust could be a remnant of the protoplanetary disk. Mostly it is inferred to be continuouslyExpand
First Detection of Hydrogen in the \beta\ Pictoris Gas Disk
The young and nearby star \beta\ Pictoris (\beta\ Pic) is surrounded by a debris disk composed of dust and gas known to host a myriad evaporating exocomets, planetesimals and at least one planet. AtExpand
Fe I in the β Pictoris circumstellar gas disk: I. Physical properties of the neutral iron gas⋆
The young planetary system β  Pictoris is surrounded by a circumstellar disk of dust and gas. Because both dust and gas have a lifetime shorter than the system age, they need to be replenishedExpand
