Brown dwarfs forming in discs: where to look for them?
Dimitris Stamatellos, Anthony Whitworth
A large fraction of the observed brown dwarfs may form by gravitational fragmentation of unstable discs. This model reproduces the brown dwarf desert, and provides an explanation t…
Protostellar discs formed from turbulent cores
S. Walch, T. Naab, A. Burkert +2
We investigate the collapse and fragmentation of low-mass, trans-sonically turbulent prestellar cores, using SPH simulations. The initial conditions are slightly supercritical Bonn…
The role of thermodynamics in disc fragmentation
Dimitris Stamatellos, Anthony Whitworth
Thermodynamics play an important role in determining the way a protostellar disc fragments to form planets, brown dwarfs and low-mass stars. We explore the effect that different tr…
The fragmentation of expanding shells I: Limitations of the thin--shell approximation
James E. Dale, Richard Wunsch, Anthony Whitworth +1
We investigate the gravitational fragmentation of expanding shells in the context of the linear thin--shell analysis. We make use of two very different numerical schemes; the FLASH…
Smoothed Particle Hydrodynamics simulations of expanding HII regions. I. Numerical methods and tests
T. G. Bisbas, R. Wunsch, A. P. Whitworth +1
We describe a new algorithm for including the dynamical effects of ionizing radiation in SPH simulations, and we present several examples of how the algorithm can be applied to pro…
Protostellar disks formed from rigidly rotating cores
S. Walch, A. Burkert, A. Whitworth +2
Abridged: We use three-dimensional SPH simulations to investigate the collapse of low-mass prestellar cores and the formation and early evolution of protostellar discs. The initial…
