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 dependence of the sub-stellar IMF on the initial conditions for star formation
E. J Delgado-Donate, C. J. Clarke, M. R. Bate
Abridged: We have undertaken a series of hydrodynamical simulations of multiple star formation in small turbulent molecular clouds. Our goal is to determine the sensitivity of the…
On the stability of self-gravitating protoplanetary discs
W. K. M. Rice, P. J. Armitage, I. A. Bonnell +1
It has already been shown, using a local model, that accretion discs with cooling times t_cool <= 3 Omega^-1 fragment into gravitationally bound objects, while those with cooling t…
Are there brown dwarfs in globular clusters?
I. A. Bonnell, C. J. Clarke, M. R. Bate +3
We present an analytical method for constraining the substellar initial mass function in globular clusters, based on the observed frequency of transit events. Globular clusters typ…
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…
Three-dimensional Calculations of High and Low-mass Planets Embedded in Protoplanetary Discs
M. R. Bate, S. H. Lubow, G. I. Ogilvie +1
We analyse the non-linear, three-dimensional response of a gaseous, viscous protoplanetary disc to the presence of a planet of mass ranging from one Earth mass (1 M) to one Jup…
