Detailed Studies of Cloud Cores: Probing the Initial Conditions for Protostellar Collapse
Philippe Andre, Arnaud Belloche, Patrick Hennebelle +1
Improving our understanding of the earliest stages of star formation is crucial to gain insight into the origin of stellar masses, multiple systems, and protoplanetary disks. We di…
The Structure of Cold Molecular Cloud Cores
D. Ward-Thompson, D. J. Nutter, J. M. Kirk +1
A brief summary is presented of our current knowledge of the structure of cold molecular cloud cores that do not contain protostars, sometimes known as starless cores. The most cen…
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…
SCUBA Polarization Measurements of the Magnetic Field Strengths in the L183, L1544, and L43 Prestellar Cores
R. M. Crutcher, D. J. Nutter, D. Ward-Thompson +1
We have mapped linearly polarized dust emission from L183 with the JCMT SCUBA polarimeter and have analyzed these and our previously published data for the prestellar cores L183, L…
