Star formation in molecular cores III. The effect of the turbulent power spectrum
S. P. Goodwin, A. P. Whitworth, D. Ward-Thompson
We investigate the effect of the turbulent power spectrum (P(k) \propto k^{-n}, with n=3, 4 or 5) on the fragmentation of low-mass cores, by means of SPH simulations. We adopt init…
The Origin of the IMF from Core Mass Functions
Simon P. Goodwin, A. P. Whitworth, D. Ward-Thompson
We examine the initial mass functions (IMFs) of stars produced by different molecular core mass functions. Simulations suggest that more massive cores produce more stars, so we pro…
A turbulent MHD model for molecular clouds and a new method of accretion on to star-forming cores
D. Balsara, D. Ward-Thompson, R. M. Crutcher
We describe the results of a sequence of simulations of gravitational collapse in a turbulent magnetized region. The parameters are chosen to be representative of molecular cloud m…
