Misaligned streamers around a galactic centre black hole from a single cloud's infall
William E. Lucas, Ian A. Bonnell, Melvyn B. Davies +1
We follow the near radial infall of a prolate cloud onto a 4 x 10^6 Msun supermassive black hole in the Galactic Centre using smoothed particle hydrodynamics (SPH). We show that a…
The role of disc self-gravity in the formation of protostars and protostellar discs
W. K. M. Rice, J. H. Mayo, P. J. Armitage
We use time-dependent, one-dimensional disc models to investigate the evolution of protostellar discs that form through the collapse of molecular cloud cores and in which the prima…
Time-dependent models of the structure and evolution of self-gravitating protoplanetary discs
W. K. M. Rice, P. J. Armitage
Angular momentum transport within young massive protoplanetary discs may be dominated by self-gravity at radii where the disk is too weakly ionized to allow the development of the…
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…
