Common envelopes in massive stars III. The obstructive role of radiation transport in envelope ejection
Mike Y. M. Lau, Ryosuke Hirai, Daniel J. Price +2
We present 3D radiation hydrodynamics simulations of common-envelope (CE) evolution involving a 12 solar mass red supergiant donor and a 3 solar mass companion. Existing 3D simulat…
The statistical properties of stars at redshift, z=5, compared with the present epoch
Matthew R. Bate
We report the statistical properties of stars and brown dwarfs obtained from three radiation hydrodynamical simulations of star cluster formation with metallicities of 1, 1/10 and…
On the origin of magnetic fields in stars II: The effect of numerical resolution
James Wurster, Matthew R. Bate, Daniel J. Price +1
Are the kG-strength magnetic fields observed in young stars a fossil field left over from their formation or are they generated by a dynamo? Our previous numerical study concluded…
A triple star system with a misaligned and warped circumstellar disk shaped by disk tearing
Stefan Kraus, Alexander Kreplin, Alison K. Young +29
Young stars are surrounded by a circumstellar disk of gas and dust, within which planet formation can occur. Gravitational forces in multiple star systems can disrupt the disk. The…
There is no magnetic braking catastrophe: Low-mass star cluster and protostellar disc formation with non-ideal magnetohydrodynamics
James Wurster, Matthew R. Bate, Daniel J. Price
We present results from the first radiation non-ideal magnetohydrodynamics (MHD) simulations of low-mass star cluster formation that resolve the fragmentation process down to the o…
Resolving numerical star formation: A cautionary tale
James Wurster, Matthew R. Bate
Resolution studies of test problems set baselines and help define minimum resolution requirements, however, resolution studies must also be performed on scientific simulations to d…
