Vortices in self-gravitating disks
G. R. Mamatsashvili, W. K. M. Rice
Vortices are believed to greatly help the formation of km sized planetesimals by collecting dust particles in their centers. However, vortex dynamics is commonly studied in non-sel…
Why are there so few hot Jupiters?
W. K. M. Rice, P. J. Armitage, D. F. Hogg
We use numerical simulations to model the migration of massive planets at small radii and compare the results with the known properties of 'hot Jupiters' (extrasolar planets with s…
Planetesimal formation via fragmentation in self-gravitating protoplanetary discs
W. K. M. Rice, G. Lodato, J. E. Pringle +2
An unsolved issue in the standard core accretion model for gaseous planet formation is how kilometre-sized planetesimals form from, initially, micron-sized dust grains. Solid growt…
Astrometric signatures of self-gravitating protoplanetary discs
W. K. M. Rice, P. J. Armitage, M. R. Bate +1
We use high resolution numerical simulations to study whether gravitational instabilities within circumstellar discs can produce astrometrically detectable motion of the central st…
