Towards a population synthesis model of self-gravitating disc fragmentation and tidal downsizing II: The effect of fragment-fragment interactions

D. H. Forgan, C. Hall, F. Meru +1

It is likely that most protostellar systems undergo a brief phase where the protostellar disc is self-gravitating. If these discs are prone to fragmentation, then they are able to…

Planetesimal formation in self-gravitating discs -- dust trapping by vortices

P. G. Gibbons, G. R. Mamatsashvili, W. K. M. Rice

The mechanism through which meter-sized boulders grow to km-sized planetesimals in protoplanetary discs is a subject of active research, since it is critical for planet formation.…

Planetesimal formation in self-gravitating discs: the effects of particle self-gravity and back-reaction

P. G. Gibbons, G. R. Mamatsashvili, W. K. M. Rice

We study particle dynamics in self-gravitating gaseous discs with a simple cooling law prescription via two-dimensional simulations in the shearing sheet approximation. It is well…

Tidal evolution of close-in giant planets : Evidence of Type II migration?

W. K. M. Rice, J. Veljanoski, A. Collier Cameron

It is well accepted that 'hot Jupiters' did not form in situ, as the temperature in the protoplanetary disc at the radius at which they now orbit would have been too high for plane…

Planetesimal Formation In Self-Gravitating Discs

P. G. Gibbons, W. K. M. Rice, G. R. Mamatsashvili

We study particle dynamics in local two-dimensional simulations of self-gravitating accretion discs with a simple cooling law. It is well known that the structure which arises in t…

Convergence of SPH simulations of self-gravitating accretion discs: Sensitivity to the implementation of radiative cooling

W. K. M. Rice, D. H. Forgan, P. J. Armitage

Recent simulations of self-gravitating accretion discs, carried out using a three-dimensional Smoothed Particle Hydrodynamics (SPH) code by Meru and Bate, have been interpreted as…
