Massive star formation: Nurture, not nature
I. A. Bonnell, S. G. Vine, M. R. Bate
We investigate the physical processes which lead to the formation of massive stars. Using a numerical simulation of the formation of a stellar cluster from a turbulent molecular cl…
Substellar companions and isolated planetary mass objects from protostellar disc fragmentation
W. K. M. Rice, P. J. Armitage, I. A. Bonnell +3
Self-gravitating protostellar discs are unstable to fragmentation if the gas can cool on a time scale that is short compared to the orbital period. We use a combination of hydrodyn…
The hierarchical formation of a stellar cluster
Ian A. Bonnell, Matthew R. Bate, Stephen G. Vine
Recent surveys of star forming regions have shown that most stars, and probably all massive stars, are born in dense stellar clusters. The mechanism by which a molecular cloud frag…
Core dissolution and the dynamics of massive stars in young stellar clusters
S. G. Vine, I. A. Bonnell
We investigate the dynamical effects of rapid gas expulsion from the core of a young stellar cluster. The aims of this study are to determine 1) whether a mass-segregated core surv…
Simulations of Spheroidal Systems with Substructure: Trees in Fields
S. Vine, S. Sigurdsson
We present a hybrid technique of N-body simulation to deal with collisionless stellar systems having an inhomogeneous global structure. We combine a treecode and a self-consistent…
On the probability of major-axis precession in triaxial ellipsoidal potentials
P. A. Thomas, S. Vine, F. R. Pearce
Orbits in triaxial ellipsoidal potentials precess about either the major or minor axis of the ellipsoid. In standard perturbation theory it can be shown that a circular orbit will…
