One-Sided Story from Disk In young analogs of the solar system, the ongoing erosion of comets and nascent planets produces dusty debris that is eventually expelled by the host star. Gas should also be released in this process when volatile ices sublimate, but it is detected less often. Using the Atacama Large Millimeter/Submillimeter Array, Dent et al. (p. 1490, published online 6 March; see the Perspective by Brandeker) mapped a highly asymmetric disk of dust and carbon monoxide orbiting the… 
Gas and dust around A-type stars at tens of Myr: signatures of cometary breakup
Discs of dusty debris around main-sequence stars indicate fragmentation of orbiting planetesimals, and for a few A-type stars, a gas component is also seen that may come from collisionally released
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, small
A SMACK MODEL OF COLLIDING PLANETESIMALS IN THE β PICTORIS DEBRIS DISK
We present a new model of the β Pictoris disk-and-planet system that simulates both the planetesimal collisions and the dynamics of the resulting dust grains, allowing us to model features and
Azimuthal asymmetries in the debris disk around HD 61005: A massive collision of planetesimals?
Context. Debris disks off er valuable insights into the latest stages of circumstellar disk evolution, and can possibly help us to trace the outcomes of planetary formation processes. In the age
Molecular Gas in Debris Disks around Young A-type Stars
According to the current paradigm of circumstellar disk evolution, gas-rich primordial disks evolve into gas-poor debris disks that are composed of second-generation dust. To explore the transition
Solution to the debris disc mass problem: planetesimals are born small?
Debris belts on the periphery of planetary systems, encompassing the region occupied by planetary orbits, are massive analogues of the Solar system's Kuiper belt. They are detected by thermal
Insights into Planet Formation from Debris Disks: I. The Solar System as an Archetype for Planetesimal Evolution
Circumstellar disks have long been regarded as windows into planetary systems. The advent of high sensitivity, high resolution imaging in the submillimeter where both the solid and gas components of

A Deep Search for Five Molecules in the 49 Ceti Debris Disk
Surprisingly strong CO emission has been observed from more than a dozen debris disks around nearby main-sequence stars. The origin of this CO is unclear, in particular whether it is left over from
A gap in the planetesimal disc around HD 107146 and asymmetric warm dust emission revealed by ALMA
While detecting low-mass exoplanets at tens of au is beyond current instrumentation, debris discs provide a unique opportunity to study the outer regions of planetary systems. Here, we report new

Stabilization of the disk around β Pictoris by extremely carbon-rich gas
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,
ON THE UNUSUAL GAS COMPOSITION IN THE β PICTORIS DEBRIS DISK
The metallic gas associated with the β 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 in this
Dynamical modeling of large scale asymmetries in the beta Pictoris dust disk
We report a new and complete model of the Pictoris disk, which succeeds in accounting for both the surface brightness distribution, warp characteristics, the outer \butterfly" asymmetry as observed
Braking the Gas in the β Pictoris Disk
The star β Pictoris hosts the best studied circumstellar disk to date. Nonetheless, a long-standing puzzle has been around since the detection of metallic gas in the disk: radiation pressure from the
A Giant Planet Imaged in the Disk of the Young Star β Pictoris
TLDR
It is shown that the ~10-million-year-oldβ Pictoris system hosts a massive giant planet, β Pictoris b, located 8 to 15 astronomical units from the star, which confirms that gas giant planets form rapidly within disks and validates the use of disk structures as fingerprints of embedded planets.
THE MINERALOGY AND STRUCTURE OF THE INNER DEBRIS DISK OF β PICTORIS

A Circumstellar Disk Around β Pictoris
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
A 40 Myr OLD GASEOUS CIRCUMSTELLAR DISK AT 49 CETI: MASSIVE CO-RICH COMET CLOUDS AT YOUNG A-TYPE STARS
The gaseous molecular disk that orbits the main-sequence A-type star 49 Ceti has been known since 1995, but the stellar age and the origin of the observed carbon monoxide molecules have been unknown.
Resonant Trapping of Planetesimals by Planet Migration: Debris Disk Clumps and Vega’s Similarity to the Solar System
This paper describes a model that can explain the observed clumpy structures of debris disks. Clumps arise because after a planetary system forms, its planets migrate because of angular momentum
Dust in Resonant Extrasolar Kuiper Belts: Grain Size and Wavelength Dependence of Disk Structure
This paper considers the distribution of dust that originates in the breakup of planetesimals that are trapped in resonance with a planet. It is shown that there are three distinct grain populations
