Convergence of simulations of self-gravitating accretion discs II: Sensitivity to the implementation of radiative cooling and artificial viscosity
W. K. M. Rice, S. -J. Paardekooper, D. H. Forgan +1
Recently it has been suggested that the fragmentation boundary in Smoothed Particle Hydrodynamic (SPH) and FARGO simulations of self-gravitating accretion discs with beta-cooling d…
Planet-planet scattering in planetesimal disks
Sean N. Raymond, Philip J. Armitage, Noel Gorelick
We study the final architecture of planetary systems that evolve under the combined effects of planet-planet and planetesimal scattering. Using N-body simulations we investigate th…
Eccentricity of masing disks in Active Galactic Nuclei
Philip J. Armitage
Observations of Keplerian disks of masers in NCG 4258 and other Seyfert galaxies can be used to obtain geometric distance estimates and derive the Hubble constant. The ultimate pre…
Predictions for the correlation between giant and terrestrial extrasolar planets in dynamically evolved systems
Dimitri Veras, Philip J. Armitage
The large eccentricities of many giant extrasolar planets may represent the endpoint of gravitational scattering in initially more crowded systems. If so, the early evolution of th…
Eccentricity of supermassive black hole binaries coalescing from gas rich mergers
Philip J. Armitage, Priyamvada Natarajan
Angular momentum loss to circumbinary gas provides a possible mechanism for overcoming the `last parsec' problem and allowing the most massive black hole binaries formed from galac…
Early planet formation as a trigger for further planet formation
Philip J. Armitage, Brad M. S. Hansen
Recent discoveries of extrasolar planets at small orbital radii, or with significant eccentricities, indicate that interactions between massive planets and the disks of gas and dus…
