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…
The chemistry of protoplanetary fragments formed via gravitational instabilities
J. D. Ilee, D. H. Forgan, M. G. Evans +8
In this paper, we model the chemical evolution of a 0.25 M protoplanetary disc surrounding a 1 M star that undergoes fragmentation due to self-gravity. We use S…
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…
