Non-convergence of the critical cooling timescale for fragmentation of self-gravitating discs
accretion accretion discs protoplanetary discs planets and satellites
2010/11/10
We carry out a resolution study on the fragmentation boundary of self-gravitating discs. We perform three-dimensional Smoothed Particle Hydrodynamics simulations of discs to determine whether the crit...
The fragmentation of expanding shells III: Oligarchic accretion and the mass spectrum of fragments
Galaxy Astrophysics (astro-ph.GA)

We use SPH simulations to investigate the gravitational fragmentation of expanding shells through the linear and non--linear regimes.
