The Fragmentation of Cores and the Initial Binary Population
S. P. Goodwin, P. Kroupa, A. Goodman +1
Almost all young stars are found in multiple systems. This suggests that protostellar cores almost always fragment into multiple objects. The observed properties of multiple system…
The formation of brown dwarfs
A. P. Whitworth, S. P. Goodwin
We review four mechanisms for forming brown dwarfs: (i) turbulent fragmentation (producing very low-mass prestellar cores); (ii) gravitational instabilities in discs; (iii) dynamic…
Observational characteristics of dense cores with deeply embedded young protostars
D. Stamatellos, A. P. Whitworth, S. P. Goodwin
Class 0 objects, which are thought to be the youngest protostars, are identified in terms of NIR or radio emission and/or the presence of molecular outflows. We present combined hy…
Simulating star formation in molecular cloud cores I. The influence of low levels of turbulence on fragmentation and multiplicity
Simon P Goodwin, A P Whitworth, D. Ward-Thompson
We present the results of an ensemble of simulations of the collapse and fragmentation of dense star-forming cores. We show that even with very low levels of turbulence the outcome…
Why do starless cores appear more flattened than protostellar cores?
Simon P Goodwin, D. Ward-Thompson, A. P. Whitworth
We evaluate the intrinsic three dimensional shapes of molecular cores, by analysing their projected shapes. We use the recent catalogue of molecular line observations of Jijina et…
