3D simulations recover the critical obliquity for disc breaking predicted by semi-analytic models and reveal additional stabilization by spiral arms that can prevent breaking.
Phantom: A smoothed particle hydrodynamics and magnetohydrodynamics code for astrophysics
4 Pith papers cite this work. Polarity classification is still indexing.
abstract
We present Phantom, a fast, parallel, modular and low-memory smoothed particle hydrodynamics and magnetohydrodynamics code developed over the last decade for astrophysical applications in three dimensions. The code has been developed with a focus on stellar, galactic, planetary and high energy astrophysics and has already been used widely for studies of accretion discs and turbulence, from the birth of planets to how black holes accrete. Here we describe and test the core algorithms as well as modules for magnetohydrodynamics, self-gravity, sink particles, H_2 chemistry, dust-gas mixtures, physical viscosity, external forces including numerous galactic potentials as well as implementations of Lense-Thirring precession, Poynting-Robertson drag and stochastic turbulent driving. Phantom is hereby made publicly available.
