The evolution of planetesimal swarms in self-gravitating protoplanetary discs
Joe Walmswell, Cathie Clarke, Peter Cossins
We investigate the kinematic evolution of planetesimals in self-gravitating discs, combining Smoothed Particle Hydrodynamical (SPH) simulations of the disc gas with a gravitational…
The Nature of Angular Momentum Transport in Radiative Self-Gravitating Protostellar Discs
Duncan Forgan, Ken Rice, Peter Cossins +1
Semi-analytic models of self-gravitating discs often approximate the angular momentum transport generated by the gravitational instability using the phenomenology of viscosity. Thi…
Smoothed Particle Hydrodynamics
Peter J. Cossins
I present a review of Smoothed Particle Hydrodynamics (SPH), with the aim of providing a mathematically rigorous, clear derivation of the algorithms from first principles. The meth…
The effects of opacity on gravitational stability in protoplanetary discs
Peter Cossins, Giuseppe Lodato, Cathie Clarke
In this paper we consider the effects of opacity regimes on the stability of self-gravitating protoplanetary discs to fragmentation into bound objects. Using a self-consistent 1-D…
Characterising the Gravitational Instability in Cooling Accretion Discs
Peter Cossins, Giuseppe Lodato, Cathie Clarke
We perform numerical analyses of the structure induced by gravitational instabilities in cooling gaseous accretion discs. For low enough cooling rates a quasi-steady configuration…
