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…
Synthetic molecular line observations of the first hydrostatic core from chemical calculations
Alison K. Young, Matthew R. Bate, Tim J. Harries +1
The first stable object to develop in the low-mass star formation process has long been predicted to be the first hydrostatic core (FHSC). Despite much effort, it has still yet to…
Disc formation and fragmentation using radiative non-ideal magnetohydrodynamics
James Wurster, Matthew R. Bate
We investigate the formation and fragmentation of discs using a suite of three-dimensional smoothed particle radiative magnetohydrodynamics simulations. Our models are initialised…
Substellar Multiplicity Throughout the Ages
Daniella Bardalez Gagliuffi, Kimberly Ward-Duong, Jacqueline Faherty +11
Substellar multiplicity is a key outcome of the formation process. The biggest challenge for the next decade will be to distinguish between the formation history, environmental con…
The statistical properties of stars and their dependence on metallicity
Matthew R. Bate
We report the statistical properties of stars and brown dwarfs obtained from four radiation hydrodynamical simulations of star cluster formation, the metallicities of which span a…
