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
TRANSIENCE OF HOT DUST AROUND SUN-LIKE STARS
In this paper a simple model for the steady state evolution of debris disks due to collisions is developed and confronted with the properties of the emerging population of seven Sun-like stars thatExpand
HOW OBSERVATIONS OF CIRCUMSTELLAR DISK ASYMMETRIES CAN REVEAL HIDDEN PLANETS : PERICENTER GLOW AND ITS APPLICATION TO THE HR 4796 DISK
Recent images of the disks of dust around the young stars HR 4796A and Fomalhaut show, in each case, a double-lobed feature that may be asymmetric (one lobe may be brighter than the other). AExpand
Steady State Evolution of Debris Disks around A Stars
In this paper a simple analytical model for the steady-state evolution of debris disks due to collisions is confronted with Spitzer observations of dust around main sequence A stars. All stars areExpand
Planet Hunters IX. KIC 8462852-where's the flux?
TSB acknowledges support provided through NASA grant ADAP12-0172 and ADAP14-0245. MCW and GMK acknowledge the support of the European Union through ERC grant number 279973. The authors acknowledgeExpand
Collisional processes in extrasolar planetesimal discs – dust clumps in Fomalhaut's debris disc
This paper presents a model for the outcome of collisions between planetesimals in a debris disc, and assesses the impact of collisional processes on the structure and size distribution of the disc.Expand
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 populationsExpand
Molecular Gas Clumps from the Destruction of Icy Bodies in the β Pictoris Debris Disk
TLDR
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
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 momentumExpand
The Vega debris disk: A surprise from spitzer
We present high spatial resolution mid- and far-infrared images of the Vega debris disk obtained with the Multiband Imaging Photometer for Spitzer (MIPS). The disk is well resolved, and its angularExpand
