Oort cloud asteroids: Collisional evolution, the Nice Model, and the Grand Tack
Andrew Shannon, Alan P. Jackson, Mark C. Wyatt
If the Solar system had a history of planet migration, the signature of that migration may be imprinted on the populations of asteroids and comets that were scattered in the planet…
The spherical Brazil Nut Effect and its significance to asteroids
Viranga Perera, Alan P. Jackson, Erik Asphaug +1
Many asteroids are likely rubble-piles that are a collection of smaller objects held together by gravity and possibly cohesion. These asteroids are seismically shaken by impacts, w…
Gas and dust around A-type stars at tens of Myr:signatures of cometary breakup
J S Greaves, W S Holland, B C Matthews +6
Discs of dusty debris around main-sequence star indicate fragmentation of orbiting planetesimals, and for a few A-type stars, a gas component is also seen that may come from collis…
Eight billion asteroids in the Oort cloud
Andrew Shannon, Alan P. Jackson, Dimitri Veras +1
The Oort cloud is usually thought of as a collection of icy comets inhabiting the outer reaches of the Solar system, but this picture is incomplete. We use simulations of the forma…
Molecular Gas Clumps from the Destruction of Icy Bodies in the Pictoris Debris Disk
W. R. F. Dent, M. C. Wyatt, A. Roberge +11
Many stars are surrounded by disks of dusty debris formed in the collisions of asteroids, comets and dwarf planets. But is gas also released in such events? Observations at submm w…
Debris from giant impacts between planetary embryos at large orbital radii
Alan P. Jackson, Mark C. Wyatt, Amy Bonsor +1
We consider the observational signatures of giant impacts between planetary embryos. While the debris released in the impact remains in a clump for only a single orbit, there is a…
