A Dynamical Mass Estimate from the Magellanic Stream
Peter Craig, Sukanya Chakrabarti, Stefi Baum +1
We present a model for the formation of the Magellanic Stream (MS) due to ram pressure stripping. We model the history of the Small and Large Magellanic Clouds in the recent cosmol…
Non-ideal magnetohydrodynamics vs turbulence II: Which is the dominant process in stellar core formation?
James Wurster, Benjamin T. Lewis
Non-ideal magnetohydrodynamics (MHD) is the dominant process. We investigate the effect of magnetic fields (ideal and non-ideal) and turbulence (sub- and transsonic) on the formati…
Non-ideal magnetohydrodynamics vs turbulence I: Which is the dominant process in protostellar disc formation?
James Wurster, Benjamin T. Lewis
Non-ideal magnetohydrodynamics (MHD) is the dominant process. We investigate the effect of magnetic fields (ideal and non-ideal) and turbulence (sub- and transsonic) on the formati…
Shaken and stirred: the effects of turbulence and rotation on disc and outflow formation during the collapse of magnetised molecular cloud cores
Benjamin T. Lewis, Matthew R. Bate
We present the results of eighteen magnetohydrodynamical calculations of the collapse of a molecular cloud core to form a protostar. Some calculations include radiative transfer in…
The dependence of protostar formation on the geometry and strength of the initial magnetic field
Benjamin T. Lewis, Matthew R. Bate
We report results from twelve simulations of the collapse of a molecular cloud core to form one or more protostars, comprising three field strengths (mass-to-flux ratios, μ, of 5,…
Smoothed Particle Magnetohydrodynamics: A State of the Union
Benjamin T. Lewis, Matthew R. Bate, Terrence S. Tricco
Obtaining a stable magnetohydrodynamical (MHD) formalism in SPH - i.e. smoothed particle magnetohydrodynamics (SPMHD) - has proven remarkably difficult. To implement MHD requires t…
Stable smoothed particle magnetohydrodynamics in very steep density gradients
Benjamin T. Lewis, Matthew R. Bate, Joseph J. Monaghan +1
The equations of smoothed particle magnetohydrodynamics (SPMHD), even with the various corrections to instabilities so far proposed, have been observed to be unstable when a very s…
Smoothed particle magnetohydrodynamic simulations of protostellar outflows with misaligned magnetic field and rotation axes
Benjamin T. Lewis, Matthew R. Bate, Daniel J. Price
We have developed a modified form of the equations of smoothed particle magnetohydrodynamics which are stable in the presence of very steep density gradients. Using this formalism,…
